The following is a message I posted a few months ago and for which I got
a reply for a debug trace. I tried to manage to get it but the problem
was randomly generated and a couple of times I got 100MB files and I
couldn't find any useful info. Tracing stopped without showing any
malfunction or anythingh different.

A few week later I had to reinstall WinXp and discovered that MSI
provides a patch for the USB driver and that restarting Linux the USB
devices were not working because ehci_hcd and uhci_hcd were assigned
different interrupts. I thought it was some problem with the PnP in the
BIOS so I entered configurationand to reset PnP, but at the same time I,
accidentally, disabled USB2.0 and my WG111 started to work correctly.
When I discovered that USB2.0 was disabled I reenabled it but, again, I
got disconnections. I went back and it works.
Althought I don't know the purpose of the patch supplied by MSI I think
that the problem cames from the ehci_hcd driver that cannot handle the
hardware of the VIA chipset.
I hope that this bit of information may help, thought it is not a
