Modern computers have 4 to 5 usb Ports for Mouse, key board, camera, Mobiles Digital cameras and much more. You are with this "SUB Device not Recognized"

IT IS BECAUSE
Motherboard which performs all functions including usb. Sometimes the motherboard needs to be “Rebooted”. when u unplug ur cable than the small microprocessor on the motherboard reload the drivers and your USB ports should be back to recognizing all devices!

Disable Autoplay of Audio CDs , Blank CD or DVD media and USB Drives in XP and Vista

Feel bad when autoplay notification tease again and again here is simple trick to disable it (For XP)

Steps :

• To get to the configuration screen for this setting, go to Start Menu \ Run and type in:

 gpedit.msc

• You will see the Group Policy window. You should select Administrative Templates \ System in the tree view:

• You will see an item in the right side pane called “Turn off Autoplay”

• Double click the item, and set the radio button to Enabled, and change the “Turn off Autoplay on” to All Drives.

• Now you should be safe from the autoplay monster.

Disable AutoPlay in Windows Vista
Windows Vista’s AutoPlay options are a great improvement over Windows XP in terms of flexibility, but unfortunately there are so many options that it can be confusing, especially since there’s no specific mention of USB Flash drives in the options.

• Open your Control Panel, and then click on “Play CDs or other media automatically” to open the AutoPlay dialog.

Disable AutoPlay Globally

• The quickest way to disable AutoPlay entirely is to just uncheck the box for “Use AutoPlay for all media and devices”, which should usually work.

Disable for a Single Type

• You can choose a setting in the drop-down menu for a single type of drive, for instance Audio CD in this example. For this to work you’ll have to make sure to keep the global autoplay option on, and then choose the specific setting in the drop-down.

Disable for just Removable (flash) Drives

• The problem here is that while there are settings for Audio CDs and DVDs, there’s nothing specifically for USB flash drives. Windows will determine the drive type based on the content it finds on the flash drive itself, so that’s what we’ll need to change.
• In order to disable AutoPlay for the removable drives, you should change all of the following to Take no action: Software and games, Pictures, Video files, Audio files, and Mixed content.

Disable Through Group Policy

• A number of readers have written in complaining that the option to disable autoplay isn’t working for them, so if you’d like to disable it entirely you can use the Group Policy editor on the Business and Ultimate versions of Vista.
• Open up gpedit.msc through the start menu search box, browse to Windows Components \ AutoPlay Policies, and change the value of “Turn off Autoplay” to enabled.

•  You can choose whether to disable for just removable devices, or entirely. I’m not sure if that makes any sense, however.

Disable with Registry Hack
The Group Policy editor is not available on Windows Vista Home editions, so I’ve also included the registry tweak to disable AutoPlay entirely.
Download and unzip this registry hack and then double-click on the appropriate file.

• DisableAutoPlay.reg will disable autoplay entirely.
• DisableAutoPlayRemovable.reg will disable autoplay on removable devices.

Disable AutoPlay of Blank CD or DVD media

• Ubuntu will automatically launch a CD burning tool when you insert a blank data cd or dvd. This can sometimes interfere with something else you are doing right at that moment.
• To disable this, navigate to System \ Preferences \ Removable Drives and Media:

• Uncheck the box, and you will no longer autoplay blank discs.

Protect Your Computer From USB Viruses-Top 5 Security Tips

With increasing anti-virus security in place against email-aware viruses and malware, hackers are turning their attention to less well-defended routes such as USB drives. This is the latest method that’s used by hackers to torment innocent users. However, there are ways you can protect your computer from USB and Pen drive viruses.

1.Block USB Viruses

Invest in an excellent anti-virus program that has built in USB virus scan and remover. These anti-USB virus scan programs not only protect your computer from USB Autorun viruses but can also clean worms, Trojans and viruses in your USB memory sticks.You can try anti-virus programs for USB virus such as USB Virus Scan, USB Drive Antivirus and so on.
 
2.Disable Your Computer’s Autorun Feature
 
When you plug in a USB drive stick into your system, the Autorun feature initiates automatically. If your USB contains any virus programs, it’ll use the Autorun feature to infect your computer. To protect your computer, disable the Autorun feature.You can disable the Autorun feature via the Control Panel.
Alternatively, you can use antivirus software to disable and enable the Autorun feature whenever you want. Additionally, these USB blocking softwares allow system administrators to specify which removable storage drives users can access.

3.Update Your Device Driver

Keeping your USB device driver updated is a good way to ensure greater stability for your USB drives. While this won’t help eradicate USB viruses, USB device drivers are constantly updated to block viruses and deliver timely warnings. You can update your USB device drive from your Windows Computer Management feature in the Control Panel.

4.Use USB Firewall Software

USB firewalls prevent Windows OS from processing malicious programs when a virus infected portable USB device is opened. USB firewalls monitor only your USB devices, and not your CD and DVD drives. By using USB firewalls, you’ll be enabling a basic level of protection from the autorun.inf viruses that spread from portable USB devices.

5.Always Safely Remove USB Devices

Viruses are sometimes created via damaged documents. If you are transferring a set of files to your USB drive, make sure the transfer is complete before you eject the device. Always use the Safely Remove Hardware feature of Windows OS. This is because partially transferred or damaged files can in turn corrupt other files on your USB drive.
