Hello, Any USB flash drive that I have purchased, my computer hp-1040n with XP will not recognize. You don't hear the USB noise when you plug them into the port. I've tried plugging them into every USB port, but it still never shows it. The lights on the Flash drive will flash at first, then nothing. All of these do work on my laptop with XP. The USB ports on the HP 1040n do recognize my mp3 player, joy stick, epson printer, Hp scanner, and other usb devices. So the ports are working. I also have tried an extrenal hard drive, the HP 1040n will not recognized that either, but again, my lap top does. It appears that it doesn't like storage drives. Any sugguestions? Thanks Crazy!
