Mengatasi Problem "USB Device Not Recognized" Pada Windows 7

Pagi ini tiba-tiba komputer saya muncul pop up peringatan "USB Device Not Recognized" di pojok kanan bawah ketika saya menancapkan flashdisk dan modem GSM. Padahal hari-hari sebelumnya tidak pernah ada masalah tersebut.
Peringatan tersebut : 

USB Device Not Recognized
One of the USB devices attached to this computer has malfunctioned, and Windows does not recognize it. For assistance in solving this problem, click this message.

Saya cek pada Windows Device Manager, memang terdapat error (tanda seru) pada salah satu root Universal Serial Bus Controller.

Berikut tips dan trik untuk mengatasi problem tersebut:

1. Pastikan bahwa semua driver terinstall dengan benar. Ingat-ingat bahwa dalam beberapa hari ini tidak melakukan upgrade driver atau melakukan instalasi hardware pada komputer Anda. Jika iya, coba remover terlebih dahulu dan lakukan instalasi ulang.

2. Lakukan uninstall pada semua root Universal Serial Bus Controller. Hal ini untuk memastikan bahwa driver yang digunakan sesuai.

3. Cabut semua power supply yang masuk ke mainboard. Bagi Anda pengguna PC, lakukan cabut kabel power utama dari power supply yang masuk ke mainboard. Untuk pengguna notebook, cabut baterai selama kurang lebih 5-10 menit. Hal ini untuk melakukan reset USB hub pada mainboard.

4. Jika cara di atas masih belum solved juga, coba lakukan disable fitur USB 2.0 dari BIOS. Hal ini menyebabkan kemampuan USB pada komputer Anda dari sisi speed (copy data, etc) akan berkurang.

Semoga bermanfaat.

Windows 8 Tips And Tricks For Beginner

Windows 8 will be available so on every branded laptop and desktop that you will buy. Recently Microsoft has released some Demo release of OS so that people can have feel of Windows 8. To be frank, I am not happy with that. Microsoft took a drastic move, by changing the interface and adding a Metro UI on the screen. The desktop is hidden somewhere, there is no Start Menu, and many more thing. In short Microsoft made is very simple. But still people are not really use to that. We always have a tradition of using the Start Menu for all our needs. Metro UI just offer you a quick access to your favorite applications, but on the same hand it is bulky when you keep on installing programzs. Still Windows 7 is my favorite. I had tested Windows 8 for a while and accumulated a set of Tips and Tricks that will help you to make it more better. Along with that there are series of threads which you can read and get more information on the same.

Getting the Start Menu back :
Windows 8 does not comes with Start Menu and this is not actually correct. Because by default every Windows user tries to look for Start Menu. Luckily there are some tweaks. But it does not look so better. There are third party applications which can add Start Menu. You just need to download then and run the setup. There are also some classic shell applications which are available for free on web. But remember that they are all third party software. There is no stability guarantee. Soon when Windows 8 gets common, we will be able to see Windows 8 to Windows 7 Transformation pack. It looks developers has yet not started working on it. For the time being keep using the Metro UI.

Desktop :
You can access Desktop by pressing Windows key + D. It is the same desktop like in Windows 7, but the only thing it lacks is Start Menu. Basic navigation can be done through arrow keys by pressing them left to right. There are columns on the screen which gives you details or glimpse of application icons and your documents. This became very messy when you have many icons. The screen allow you to group icons as per your choice. For example you can add all set of Words files at one side and Excel on the other. It is easy for common applicatinos, games, bookmarks, etc. 

Quick Access Menu :
On the screen right click on the bottom left. You can see a Quick Access Menu. This menu offers you easy link of Desktop, Control Panel, Task Manager, etc. Below is a small screenshot that can provide more highlight on the same. In the same way to shutdown Windows 8 just use Alt+F4. You can find the menu on the right side. 

Navigation:
Windows 8 new interface is quite colorful and friendly but beginner might find a bit difficult to deal with it. On touch screen monitor or Tablet you have to swipe left or right to scroll the screen and tap on any tile to access it. On regular desktop you have to spin the mouse wheel to scroll backwards and forwards. You can Press Home or End key from keyboard to navigate form one end of the screen to other. In order to start a particular tile you can either tap on it or use cursor for selecting it. Just like in windows 7 you can press Windows key to return to the Start screen. In order to unpin or remove an application from tile you can simply right click on that application and select unpin or swipe it down and replace it with other tiles around.

App groups:
In order to organize random order of the app in organized manner you can create separate groups. You just have to click on 'minus' icon in the bottom right corner of the screen which is used for zooming out. Once you zoon out you will be able to drag and drop new group around. You can name the group and add 20 or 30 apps in organized manner.

Search applications:
For searching an application hold down the Windows key and press Q or you can simply right-click an empty part of the Start screen or swipe your finger upwards and select “All Apps” option. Once you select or tap on “All Apps” option you will be presented with list of all the application that you might have installed. You can now go through them and launch the application that you might be looking for.

Easy access:
If you want to access any application easily rather than searching for it all the time you can pin it to the Start screen. In order to pin an application first type the name of the application in search system, right click on it once it appears in Apps Search screen and click on “'Pin to Start' option. In case you are using touchscreen monitor than you will have to press and hold the icon, flick down and select 'Pin to Start' option. Once you have pinned it, it will appear to the far end, you can change its position by dragging and dropping it anywhere on the screen.

Check out application that might be running:
There is no task bar to find out which application is running in the background in case you launch some application and press windows key to move to the start screen. However, you can press Alt+Tab and you will be presented with list of application that might be running. You can also press Ctrl+Shift+Esc to see all you’re running apps in the Task Manager in case you need extra detail of the applications running.

Closing an application:
You might find quite easy to launch an application by simply clicking on it or tapping its tile but closing the same can be a question for beginners. There is no close buttons, anyways you can close down any application by moving the mouse cursor up to the top of the screen, as soon as regular mouse pointer turns to icon of a hand you can hold down the left mouse button and drag the application that you want to close down the screen. By default when you switch to some something else, your application gets suspended. You can Ctrl+Shift+Esc to launch Task Manager and end task of any application you want just like we used to do in windows 7.

Accessing Internet Explorer:
You can launch Internet Explorer by clicking on its tile from the Start menu. However after launching it you will get a full-screen version without toolbars, menus or sidebars. In that case you can Right-click an empty part of the page or flick your finger downwards and you will get the option for creating and switching between the tabs. In order to get back full desktop version of Internet Explorer simply click on spanner icon.

Running 2 applications side by side:
You can run 2 applications side by side in windows 8 and for that Swipe from the left. Once you do that your last application will turn into a thumbnail and will be displayed in sidebar pane where as your current application will cover up the rest of the screen. You can easily swap between both applications by swiping again.

Making larger application tile smaller:
Some windows application might have large tile icon where as some might have small icons. In order to make larger application tile smaller you can just Right-click on the application you want and select Smaller or larger option according to the current status of that app. smaller option shrinks an application to half the size of larger icons.

Uninstall or unpin an application:
You can unpin an application just like you pinned it, you just have to select 'Unpin from Start' option for that. In case you want to uninstall any application completely rather than unpinning it than you can select uninstall option. Uninstall option is in the same menu where 'Unpin from Start' is.
Apps and privacy:
Windows 8 application pinned to the start screen will use your name, location and account picture by default. In case you don’t want them to get expose than you can press Win+I > Click on More PC Settings > select Privacy and click relevant buttons for disabling the details you want.

Disable the lock screen:
You can disable Windows 8 lock screen for booting in to windows as fast as possible. In order to do that launch GPEdit.msc > Computer Configuration > Administrative Templates > Control Panel > Personalization and double-click 'Do not display the lock screen' > Select Enabled, click OK, reboot your system and you are done. You won’t get the same Windows 8 lock screen again.
In case you are not able to find out GPEdit.msc than you can search for 'mmc'. Now in the File menu click on 'Add/Remove Snap-in', click on 'Group Policy Object Editor' and click on Add. Once you get 'Select Group Policy Object' dialog box, click on Browse, click on “'This Computer” for editing the Local Group Policy object.

Installing anything:
You are just allowed to install anything from Windows store and not form any other source. If you want to install application form other source than you will have to enable 'Allow all trusted apps to install' option. For that launch GPEdit.msc > Computer Configuration > Administrative Templates > Windows Components > App Package Deployment > double-click 'Allow all trusted apps to install', select Enabled and click on ok to save the changes.

Logging in automatically:
In case you remove lock screen you will be asked for logging in manually every time you start your system. However you can deal with it easily, you just have to Hold down Windows key, press R, type 'netplwiz' without quotes and hit enter. Once you get User Accounts dialog box, uncheck "Users must enter a user name and password to use this computer" box and click OK. You will have to enter the user name and password of the account that you might be willing to get logged in automatically and restart your system. After these changes you won’t be asked for logging in manually upon starting the system.
Replacing Windows 8 Start menu with regular Start menu:
If you don’t like Windows 8 Start menu than you can replace it with regular Start menu by downloading and installing software called ViStart or Start8 .
Taking screen shot:
For taking screen shot in windows 8 you will have to hold down Windows key and press PrtSc. However image won't get saved to the clipboard instead it will get saved to your My Pictures folder naming Screenshot.png followed by Screenshot (1).png, Screenshot (2) if you press same buttons repeatedly.

Setting Windows Photo Viewer as default option for opening an image:
Simply double clicking on image file within Explorer won’t open it in Photo Viewer window. However you can set Windows Photo Viewer as default option for opening an image.
Just go to Control Panel > Programs > Default Programs > Select “Set your default programs” > Click on ‘Windows Photo Viewer” > click on 'Set this program as default' or select 'Choose default' options in case if you want to open specific type of files with Photo Viewer.

Windows 8 File History:
Windows 8 File History feature is capable of backing up or libraries, desktop, contacts and favorites to other storage media regularly and automatically. You just have to connect a USB flash drive and configure the same for storing backup using File History. In order to set it up go to Control Panel > System and Security > File History > Click on “Exclude Folders” and select the folders that you want to get backed up. You can go through the Advanced Settings for choosing backup frequency, for changing drive for backup and for enabling this feature on with settings you want.

Cara Mendengarkan Radio Online Internet

Radio merupakan salah satu media komunikasi elektronik yang paling lama. Dimana kemunculannya menjadikan daya tarik tersendiri bagi masyarakat dunia. Orang berbondong-bondong duduk menunggui sebuah kotak sambil menikmati kopi ataupun camilan untuk mendengarkan isue-isue terkini.
Bahkan pada jaman penjajahan, radio merupakan media komunikasi untuk membangkitkan semangat juang rakyat Indonesia. Kita pernah mendengar cerita seorang orator ulung Bung Tomo yang membangkitkan semangat juang pemuda Indonesia untuk melawan Belanda.
Saat ini, seiring dengan perkembangan dunia teknologi informasi, untuk mendengarkan radio tidak harus dengan perangkat reciever dengan menggunakan frekuensi SW, FM, dll. Perusahaan broadcast radio pun mulai beralih dengan memanfaatkan streaming internet sehingga masyarakat dapat mendengarkan radio secara online dari internet tersebut.
Disini saya akan coba share bagaimana cara mendengarkan radion online pada salah satu web yang sering saya kunjungi karena menurut saya lumayan lengkap link ke radio-radio onlinenya.
1. Buka alamat http://www.surfmusic.de 
2. Klik menu pada bagian kiri, sebagai contoh jika kita ingin mendengarkan radio online dari indonesia, klik Asia --> klik Indonesia nanti akan muncul list radio online yang ada di Indonesia.

Radio Online Asia


List Radio Online Indonesia
 3. Klik Listen Live untuk mendengarkan salah satu channel
4. Ketika muncul pop up windows, silakan menunggu karena add on player pada browser akan melakukan buffering terlebih dahulu (lama bufferring tergantung dari kecepatan koneksi internet Anda)


Pop Up Add On Radio Online
 5. Selamat mendengarkan dan menikmati radio online.

Semoga bermanfaat.

Apa Perbedaan AdSense dan AdChoices?

Kemarin sempat mendapat pertanyaan tersebut oleh seorang kawan yang mulai bergelut di dunia PPC iklan terutama GA (Google Adsense). Kawan saya ini melihat, pada awal melakukan mendaftaran, iklan GA pada signature bawah terdapat tulisan "ads by google" atau "iklan oleh google".
Saya sendiri sedikit bingung juga jawabnya, karena selama ini, blog yang saya bikin selalu menampilkan iklan GA dengan signature "AdChoices".

Jurus jitu bertanya ke Mbah Google dan mendapat referensi dari berbagai situs salah satunya menyebutkan sbb:

"AdChoices adalah standar internasional yang digunakan, secara bertahap semua “ads by Google / Iklan oleh Google” akan diganti ke AdChoices"

Jadi, dapat ditarik kesimpulan bahwa iklan GA yang mendapat signature "AdChoices" adalah merupakan iklan dari google yang terbaru.
Sedang yang masih mempunya signature "ads by google" atau "iklan oleh google" ke depan akan berganti ke signature "adchoices"

Semoga tulisan sedikit ini dapat membantu menjawab pertanyaan dari di atas.

Apa Itu IP Address?

Para pembaca pasti sudah mengetahui IP Address (Internet Protocol Address), danjuga sering menggunakan mahluk ini. Contohnya, ketika melakukan setting IP di Notebook, PC.
Kalau kita lihat yang biasa kita pakai, kita sering menemukan IP Address (Manual or DHCP), Subnet Mask, Gateway, dan DNS. 

Dalam kegiatan sehari hari bisa kita ibaratkan kalau kita mengirim surat menyurat memakai jasa POS. Alamat yang kita tuju harus jelas, Kelurahan, gang, no rumah, kode pos. Nah IP Address itu di ibaratkan alamat dari suatu rumah. Apabila kita tidak memberikan alamat yang jelas, surat atau paket tidak akan terkirim de tempat tujuan.

IP Address adalah singkatan dari Internet Protocol Address, yaitu suatu identitas numerik yang di labelkan kepada suatu alat, misalnya komputer atau printer yang terdapat dalam satu jaringan komputer yang menggunakan internet protocol sebagai sarana komunikasi.

Fungsi dari IP Address:
·         Alat identifikasi host atau antar muka jaringan
·         Alamat lokasi jaringan

IP Address ada dua yaitu IP.V4 dan IP.V6, namun pada kesempatan kali ini kita membahas mengenai IP.V4

IP Address V4 di bagi 5 kelas yaitu, A, B, C, D dan E

Range IP Address

Pembagian kelas kelas IP berdasarkan dua hal,yaitu Network ID dan Host ID.

Network ID adalah,bagian dari IP Address yang menunjukan di jaringan mana komputer tersebut berada.
Host ID, menunjukan workstation,server, router, dan semua TCP/IP lainnya dalam jaringan tersebut.

Dalam suatu kelas IP, misal kelas C.  192.168.1.0
Berapakah host yang bisa di dapat?

Rumusnya : Jumlah Host (H) = 2h -2

Pembaca pasti ada yang bertanya kok di kurangin 2.
Kenapa harus di kurangin 2, karena di tiap kelas IP. Ada Network Address dan Broadcast Address. Yaitu.
Network Address – IP Awal dari sebuah kelas.
Broadcast Address – IP akhir dari sebuah kelas

Contoh di kelas C. IP. 192.168.1.0

Network address : 192.168.1.0
Host : 192.168.1.2 – 192.168.1.254
Broadcast Address : 192.168.1.255

Jaringan Dasar Komputer - OSI 7 Layer

NETWORKING Merupakan jaringan antar komputer yang menghubungkan satu komputer dengan jaringan lainnya. untuk menyusun jaringan ini, diperlukan perencanaan dari jaringan yang dibangun yang disebut dengan topologi.

Networking di bagi menjadi 3, yaitu:
·         LAN (Local Area Network)
·         WAN (Wide Area Network)
·         MAN (Metropolitan Area Network)

Dalam jaringan Komputer dikenal istilah Layer OSI, Layer OSI ini merupakan Sebuah standar komunikasi yang diterapkan dalam Komunikasi Komputer, OSI yang merupakan Kepanjangan dari Open System Interconnection merupakan Kumpulan Layer-layer yang tidak saling bergantung namun saling berkaitan satu sama lain.

Model OSI ini dibentuk karena pada awalnya dimana IBM dan DEC membuat alat Komunikasi yang berbeda sehingga kedua perangkat dari perusahaan yang berbeda ini tidak dapat saling berkomunikasi. Oleh karena itu, OSI dibentuk agar semua perangkat Komunikasi data dapat menerapkan standar penggunaan komunikasi sehinga tidak terjadi diskomunikasi diantara perangkat-perangkat tersebut.


OSI 7 Layer

Application (layer 7)
layer Application Berfungsi sebagai antarmuka dengan aplikasi fungsionalitas jaringan, mengatur bagaimana aplikasi dapat mengakses jaringan, dan kemudian membuat pesan-pesan kesalahan.

Presentation (Layer 6)

Hati- Hati Penipuan Via Telepon

Hati-hati untuk teman-teman pembaca terkait maraknya penipuan via telepon yang akhir-akhir ini sering terjadi. Saya barusan saja ditelepon oleh salah satu nomor yang tidak saya kenal dan langsung memancing informasi pribadi.
Nomor telpon yang digunakan adalah 085770332449.
Ketika diangkat tidak langsung memperkenalkan nama maupun identitas. Langsung menanyakan:
"Kamu dimana?"
"Posisi dimana?"
"Masih kenal suara saya ga? "
"Coba ingat-ingat dah... masak ga kenal suara saya? "
Klo kita coba mengingat, dia akan mencoba menjadi orang yang benar-benar kita kenal. Ketika saya menyebut nama salah seorang teman, langsung dia bilang "Lha kamu pikir sapa...iya..saya memang (sebut nama) "
Nah...ini aka menggiring kita ke posisi bahwa dia memang teman kita. Dia langsung bercerita kalau lagi di pos polisi suatu perempatan dan akan ditilang. Dia meminta tolong untuk bilang ke seorang polisi bahwa dia lupa bawa surat kelengkapan kendaraan dan bersedia untuk membantu mengambilkan surat2.
Telepon akan beralih ke seorang yang mengaku polisi dan bilang "teman kamu akan saya tilang jika tidak dapat menunjukan surat2 kelengkapan "
Intinya, polisi tersebut akan melakukan proses hukum kepada seseorang yang mengaku teman saya, kecuali saya dapat membantu dengan melakukan transfer pulsa ke nomor tertentu (saya lupa mencatatnya) sebesar 100 ribu.
Ketika polisi tersebut mengatakan hal seperti itu, langsung dalam benak saya ini adalah penipuan. Kebetulan saya lagi di depan komputer dan search dengan keyword 085770332449 di google. Terlihat jelas bahwa nomor tersebut merupakan nomor untuk penipuan via telepon.

Hasil Pencarian Google Nomor 085770332449

Untuk teman-teman pembaca, berhati-hatilah jika menerima telepon dari nomor yang tidak dikenal. Bukan untuk berprasangka buruk, tetapi hal ini untuk keamanan kita agar ruang gerak penipu semakin sempit.

Semoga bermanfaat.

Mengatasi Problem Printer Dot Matrik Sering Menyobek Kertas (Epson LQ 2170, LQ 2180, LQ 2190)

Printer Epson LQ 2190
Fungsi printer dotmatrik saat ini masih belum bisa tergantikan dengan printer-printer jenis dari teknologi lain. Meskipun campaign dari vendor printer laser maupun printer ink makin gencar dengan menawarkan ekonomis maupun kecanggihannya. Karena hanya dengan printer dotmatrik, kita dapat melakukan printing dengan menggunakan kertas ply (2 ply, 3ply, 4ply, dst) dalam 1 waktu. Teknologi ini belum dapat ditemui pada printer dari teknologi laser maupun tinta.
Kali ini saya akan mencoba sharing terkait tshoot untuk printer dotmatrik merk Epson untuk Tipe LQ 2170, LQ 2180 dan LQ 2190 dimana problemnya adalah ketika proses printing sering menyobek kertas/pita ribbon.
Ada beberapa kemungkinan yang menyebabkan kerjadian ini.
1. Jarum head printer aus/tajam
Untuk problem jarum head printer yang aus/tajam ini biasanya disebabkan karena pemakain. Selain menyobek kertas/pita ribbon, biasanya problemnya juga hasil cetakan seperti angin-angin/bergaris. Solusi yang paling cepat adalah repair jarum head ke vendor. Harga service per mata jarum untuk daerah saya berkisar antara 25rb - 50rb tergantung dari kerusakan. Untuk yang mempunyai budget lumayan tebal dapat langsung beli baru dengan harga berkisar 700rb - 950rb.

2. Pita tidak dapat berputar
Problem ini sangat sering terjadi di kantor saya dimana pita printer macet (tidak dapat berputar) sehingga ketika proses printing, jarum head hanya melakukan ketukan pada satu lokasi. Kejadian ini karena user sering melakukan isi ulang pita tanpa mengganti rumah pita. Menurut pengalaman saya, rumah pita dapat berjalan bagus hanya untuk 4-5 kali untuk penggunaan pita refill. Apalagi jika mekanik yang berputar di dalam rumah pita terbuat dari gabus/spoon keras, biasanya akan basah karena tinta pada pita. Ada baiknya, jika sudah 4-5 kali pemakaain pita refill, belilah rumah pita baru dalam satu paket.

3. Plat Head printer bengkok
Jika kedua hal di atas Anda sudah yakin tidak terdapat masalah, kemungkinan lain adalah plat head printer bengkok dimana ketika proses printing akan menyobek kertas yang berjalan. Untuk memastikan, lepas head printer dari dudukannya, dan cabut plat kecil (gambar di bawah) yang ada di depan head printer. kemudian pasang kembali head printer dan lakukan test print.

Pengenalan Kabel Cross Dan Straight


Model Kabel UTP Cat5
Bagi yang tiap hari berkutat dengan dengan dunia jaringan komputer, pasti tidak akan asing dengan istilah kabel cross dan kabel straight. Kedua model kabel dibuat dengan fungsi masing-masing.
Kabel Cross:
Kabel cross berfungsi sebagai berikut:
1. Menghubungkan PC dengan PC secara langsung atau istilah lainnya pair-to-pair
2. Menghubungkan device dengan device, contoh hub dengan hub yang tidak mempunyai port Uplink / MDI/X.

Koneksi hub to hub
Kabel Cross mempunyai urutan yang saling menyilang di kedua konektornya,  seperti terlihat pada gambar di bawah ini


Urutan kabel cross


Dimana hubungan antar konektor yang satu dengan lainya mempunyai hubungan PIN yang berbeda,  sebagai ilustrasi PIN 1 pada Konector 1  dihubungkan dengan PIN 3 pada conector ke 2, PIN 2 pada conector 1 dihubungkan dengan PIN 6 pada Konector ke 2  dan seterusnya seperti terlihat pada gambar di atas.

Kabel Straight.
Kabel straight berfungsi untuk menghubungan antara PC dengan Switch/Hub.

Koneksi berdasarkan standar EIA/TIA-568B RJ-45 Wiring Scheme
Pair#2 is connected to pins 1 and 2 like this:

Pin 1 wire color:
white/orange
Pin 2 wire color:
