I'm sorry. list-sys looks like come from dom0. I mean sysfs from domu instead
;-)

Oh, thats new information for me :-/ I think I have not enough experience
to help on newer release. If it is on 3.0.4 working but not on 3.1 so I
think I could not further help.

If you have a not-hvm domain running, so you can try to use the same kernel
in dom0. I do this by me so if card is running in dom0 it should work in
domu, mostly too. If this will not work I think its more relatet to the
new xen release. If this will work it could be more on domu kernel.

I mean that 3.1 could usbdevices map to domu directly. I's possible that here
is a cross over problem with pci-hiding? I have no idea.
