I have a Compaq Deskpro EN and I just reformatted my Hard-Drive and reinstalled windows XP Pro. Basically, windows installed all the drivers. My question is, when i go to the Device Manager Scree, one of the question-mark devices is my USB controller. I have searched for it on both Driver-Guide and Compaq but cannot find it. Does anybody know what the USB controller Driver in a Compaq Driver is?? As in, is it part of some other driver ?? (as in what driver must I download that include the Usb controller)?? Or is it installed with windows, and I'm just stupid.
