i was typing right as you left yesterday… the file hidusb.sys or whatever it was you had coming back… that’s not the only one. I had my mouse driver that windows had hoarded in 3 different folders
did the exact same thing yours did when i went after one driver in the one location you mentioned. the file deleted, then reappeared 2 seconds later.
so here’s what to do.
boot into safe mode without the mouse if you can help it
use the search tool (win + f) and search for your driver’s name. you should get multiple hits.
delete them all, or at least cut and paste them to the desktop or whatever. reboot and try that.
btw, mine did that same thing… i wasn’t even running windows vista, much less vista sp1. this was in xp.
and for ppl other than tr1fe… he said he was trying to figure this out… and he had narrowed it down to thinking it was hidusb.sys
