Solution to fix the USB Drive not recognized problem

USBs have surely made our lives simpler and convenient. We like plugging our pen drives, flash drives and other external devices in USB ports but there is a strange problem that happens sometimes that when we insert our USB drive into the USB port we get an error message saying “USB Drive Not Recognized”.



POSSIBLE Cause:
I. you plugged/unplugged instantly your usb into another machine.
II. you plugged another usb onto your machine thus automatically installing the latters drivers.
III. connection from the usb hub has been fumbled with.
IV. electronic currents thus some minor shot circuits

The error message reads “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”. If we open the My Computer we will notice that even our drive has not been detected.
The first thing that will come to our mind is that we should try uninstall and then reinstall the USB drivers but here is the simpler solution and yes no need to edit the registry or try something in the Device Manager.
Solution for the problem:
1.    The solution is just to “Turn off the computer and unplug it from the power supply” (Unplugging is necessary as today even after turning the system off, the motherboard continues to get power).
2.    Let the system remain off for about a minute.
3.    Restart the system and wait for it to boot completely before inserting the drive again again.
Update:
You can try this solution also. Run devmgmt.msc in the run box, then click on My Computer in the Device Manager. Assuming that the USB is in inserted state, click on Scan for Hardware changes under the Action menu. USB should be detected now.
