USB 2.0 not working on A8V-E Deluxe

Hi,

I have an A8V-E motherboard, latest BIOS, WinXP SP2, and massive
trouble connecting USB 2.0 devices such as external harddisks, usb
storage, etc. These devices simply don't work in USB 2.0 mode, Windows
says "unknown device", only in USB1.1 mode they do work.

Now comes the strange thing: I have four of these boards, in four
identical PCs, hardware revision 1.03, but with different southbridge
revisions: three out of four have a VIA 8237R southbridge from week
42/2004, on the fourth one it's from week 46/2004. Now the strange
part: the board with the southbridge four weeks later does not have the
usb 2.0 problem whereas all the older ones do have that problem. I have
already swapped harddrives of those identical systems, showing that all
boards with the older southbridge revision have the problem, the newer
one doesn't.

The problem on the buggy board occurs with any USB 2.0 device I use,
under Windows as well as Linux. When I swap such a system completely,
i.e. moving the harddisk to my newer board, USB 2.0 from that system
booted works fine without any problems, the OS recognizes any USB2.0
device I attach.

Now, please tell me: is there a problem with early revisions of the VIA
southbridge? Can other users please tell me if you also have or have
not that problem?

Please do not forget to post the manufacturing date of your chip, and
maybe also the hardware revision of the board (above the PCI-E 16x
slot).

Thanks in advance for your help.

cu,

Jo
 
I had some similar issue and I've found that +Data and -Data wires of the
case cable where wrongly connected on the mobo.
I've swap them and fixed the issue.
 
RMA'd the A8V-e Deluxe board I got in February because USB 2.0 didn't
work. New board works fine. Date on south bridge chip is 03/05. Now has
a passive cooler as well. Runs a couple degrees hotter than the CPU
(Athlon 64 3000+).
