When I transfer a file to a USB flash drive, the transfer is very slow. I checked my USB host controllers and they are working fine. There doesn't seem to be any hardware problems. These are Dell GX270 computers, both running XP Professional SP3. I found no solutions on anyone's support site. The controllers are Intel. I have used Driver Max, and it reports no problems - but I wonder about that program's accuracy. Has anyone ever had this problem and figured it out?Michael Skladd
