USB Device Not Recognized

If you are getting "usb device not recognized" errors and after all your attempts to fix this problem by going through various Windows settings you still can't use your usb devices, these solutions might work for you:

1-First you need to completely power off your computer (unplug the power - or if you are using a laptop unplug the battery) not just closing it down (it may have something with residual current on the motherboard or with stray capacitance discharge).
2-If this doesn't work for you go into control panel and uninstall any driver that used for USB.
(They will be reinstalled again by Windows)
3-Delete INFCACHE.1 file (you can find it in Windows/Inf folder)

Hopefully some of these will work for you.
