Not a problem, I'll have to wait until my version of "the other side of
the story" let's me get at the computer tomorrow morning (I'm at work
now) in order to get the lspci -v to you but until then I have some
updated URL's for you to work with...

Here is the forum where I tracked the symptoms of the problem, there
signal to noise ratio is not the greatest but there might be some
additional information in there that might help you out:
http://www.msi.com.tw/resellers_club/forum/list_article.php?id=1234

Here is the motherboard makers download of the windows driver, I
downloaded it myself to see if there was additional information provided
in the zip but alas, there wasn't a readme in there, just a windows
installer:
http://www.msi.com.tw/support/driver/others.htm

Here is a link to the same driver (I think) on VIA's website.  I didn't
find any discussions on the website discussing the problem:
http://www.via.com.tw/jsp/en/driver/detail.jsp?hDr_id=12%20%20%20%20&hDr
_os=1&hDr_ver=1.08

As for peripherals, I was experiencing the problem with a Microsoft
Intellimouse Optical:
http://www.microsoft.com/hardware/mouse/optical.asp

I will do some additional tests tomorrow morning (US, EST) when I
provide you the lspci output.  I will try the same mouse in the ps2 slot
as well as some additional usb mice and keyboards.

If there is any additional information or things you would like me to
try, let me know and I would be more than happy to give it a go.  I am a
relative newbie to the low level stuff but I am willing to try anything
you suggest.

Thanks again, Alan.
Curtis

Can you provide me

1.	The lspci -v info for your box (chip revision etc)
2.	Details ont he updated windows drivers (eg URL for)
3.	The USB devices

> Does VIA have any engineers working on linux drivers?

Directly, I don't believe so. However they do provide contact points for
some of us and have provided workarounds for other bugs. We now have a 
mechanism in place for making such requests.

Firstly however I'd like the USB folks to look at the debug and traces
to be
sure this isnt a VIA chip bug. If it is I'll take it up with VIA
