[H] XP has lost it's thumb drive drivers

[Thane Sherrington]

I've got an XP machine that won't install drivers for thumbdrives, 
even though they should be built in.  Every time I put a thumbdrive 
or card reader in the machine, it tells me an error has occured 
installing the new hardware.  Any idea how I can make sure the 
drivers in Windows are all installed?
