Hi all, I have my boss' wife's laptop as it has been having trouble detecting USB Thumb drives. So I've plugged in both the one that they've been trying and it doesn't detect. The windows sound works indicating that it's detected something but you cannot access the drive. I have tried checking disk management and the drive doesn't even show up in that. The same thumb drive works on my own laptop and numerous other ones do not pick up, whilst they work fine on other computers. It also picks up USB hard drives fine and the problems lie with all the USB ports. It's running Vista Home Basic (with Aero running oddly enough, I always thought basic omitted Aero?) and as far as I know mostly the same factory settings as when it came from DELL in th first place. It is an Inspiron 1545. Any help would be hugely appreciated.
