USB Device not recognized :Fixed

One day I plugged a USB Device into PC or Laptop. Suddenly I got a Pop up message like “USB Device not recognized” .
I unplugged and inserted again my USB. But same result i got. I tried again and again.I didn't get anything new.

This issue can be caused if any of the following situations exist:

• The currently loaded USB driver has become unstable or corrupt
• Your PC requires an update for issues that may conflict with a USB external hard drive and Windows
• Windows may be missing other important updates hardware or software issues
• Your USB controllers may have become unstable or corrupt
• Your external drive may be entering selective suspend
• Your PC motherboard may need updated drivers

Then I searched on internet for this problem, then i got some solutions. I am going to share with you,
Method I:

• Right click mouse on My Computer icon.
• Click on Manage;

• Go to Device Manager 

• Uninstall all of the devices under USB Controllers. 
• Restarted the computer, reinstalled the USB drivers, 

But the problem still did not go away!No probs try another methods.

Method 2: 

• Turn off your computer using Shut Down or pressing the power button.
• Unplug it from the wall outlet. 
• Let it sit for about a minute 
• Plug it back in.

Method 3: 

• Disable USB selective suspend setting.
• This method prevents your USB external drive from powering down.
• Click the Start button, type power plan in the Search box, then click Choose a power plan.
• Next to your currently selected plan, click Change Plan Settings.
• Click Change advanced power settings.
• Click the box to expand USB Settings, then expand USB selective suspend settings.
• Click Plugged in, then click the drop down menu and select disabled.
• If you're using a laptop, click Battery, then click the drop down menu and select disabled.
• Click Apply, then click OK.

If this doesn't resolve your issue, proceed to Method 4.


Method 4:

• Run regedt32.exe and navigate to; 

HKEY_LOCAL_Machine\SYSTEM\CurrentControlSet\Services\Usb 

• Create the Usb key if it doesn't already exist. Under this key, create a new DWORD value called DisableSelectiveSuspend and give it a value of 1. 
• Then restart the PC. 

Method 5: 

• Install your motherboard's latest chipset drivers.
• This method updates your motherboard's chipset drivers, so your computer will recognize your USB external hard drive.
• Review your computer's documentation which should contain the name of the motherboard manufacturer.
• Visit your computer manufacturer's support website. For a list of computer manufacturers' support sites, visit: http://windows.microsoft.com/en-US/windows/help/contact-support/computer-manufacturers
