USB ports work until Windows loads
LockedThis the most puzzling problem I’ve ever seen…
System overview:
Home-made system
Abit AV8 Socket 939 Motherboard
AMD Athlon 64 3400+
2.0 GB Ram (can’t remember the bus speed)
ATI All-in-Wonder 9600XT
Sound Blaster Live! 24-bitI have a computer with a USB keyboard and mouse. When I boot the computer I can access the BIOS settings and change them using the USB keyboard, but as soon as windows loads the keyboard quits working. Obviously it’s impossible to tell if any of my other USB hardware works before windows loads.
All other ports work fine, which, combined with the fact that they keyboard works in the BIOS setup screen, precludes the possibility that the motherboard is the problem.
I have reformatted the hard drive and reinstalled Windows to no avail, and the CD that came with the motherboard contains no special USB drivers of any kind. The BIOS Setup menu contains absolutely NO options regarding USB settings that I can see.
Device manager shows no USB hubs or controllers in the USB section.
As soon as Windows has loaded, any lights that WERE on that indicated that these devices were working go off.
In addition, I can’t think of any particular event that could have caused this problem. I got a message of some kind regarding a virus so I ran a virus scan which turned up nothing. It seems that my USB ports were working, then they weren’t.
This problem is even moreperplexing when you consider how many people have the opposite problem: their USB devices don’t work UNTIL Windows loads.
