All you have to do is restore/replace them and bingo, everything will work again, I didn’t even have to reboot.
Windows2k (2000), Windows XP, Vista and even Windows 7 suffer from this problem.
Basically my external mass storage (bulk storage) devices suddenly were not being seen when I plugged them in. Reinstalling the drivers was useless and just ended up saying that windows could not find the drivers needed.
Some program uninstalls those two when you uninstall it – I am not sure what, why or how but it’s yet another Windows mystery to solve.
