I reinstalled windows xp on my dell dimension 8400 and for some reason I can't use my usb port. when I connect my mp3 player for example, it does not recognize it. I llooked in device manager and next to the usb there is a yellow exclamation point. In my computer it does not show my external harddrive, which is connected by usb as well, either.
What do you make of this? Am I missing a USB Driver? I went to the dell drivers and downloads and downloaded everything I thought I needed .
Please write back to firstname.lastname@example.org if you have any ideas.
