Windows XP Home SP2 My system stopped recognizing my Canon Powershot75 when I plug it into USB port - I tried using a card reader and the system didn't recognize that either. I think the USB drivers in System32/Drivers must have been corrupted and want to use my XP Disc to replace the System32 Drivers with those on the XP installation disk - but am not sure how to do it - The XP disc has the drivers in a '.cab' file. Can anyone give some insight? Many thanks Michael
