windows 7 32bit has been giving me this error message last few days that it does not recognise my usb flash drive.this happens no matter which usb port i plug it into.my external hdd works no problem as does my usb mouse,the flash drive did work with no issues occuring until about two days ago.
i have not updated anything with at least a week and neither has auto updates. when flash drive is attached under device manager it reads "unknown device" for the flash drive?
i uninstalled all usb drivers
,restarted windows,windows then detected and installed drivers, attached flash drive again and still same message.i have searched for solutions on this site but i just want to know what might have caused this problem? the fact that the flash drive did work and now will not is what is bugging me.i do not want to go updating bios and stuff like that as i am nervous of messing with things that could wreck the os
