Hey everybody,

i have a problem getting the usb interface running in my domU. I
successfully booted my dom0 and the log says "/pciback 0000:00:1d.7:
seizing device" (so did the parameters in grub.conf etc.)
/ I also successfully started the virtual machine (domU) with "xm create
xmDebian pci=0000:00:1d.7" with no errors.
BUT when i connect to the domU machine and make a "lspci" it shows
nothing...no devices...

The Log of the VM (domU) says:
Oct 14 17:53:38  kernel: Allocating PCI resources starting at 10000000
(gap: 04800000:fb800000)

Can anybody help me getting the usb-interface running in my domU?
Iam Using eisxen as dom0 but it doesnt make any difference to any other
xen-system as i think. As DomU i tried debian and eisfair.

in domU: If i do a "cat /proc/bus/pci/devices" it also shows
nothing...(there is no /proc/bus/usb/devices)

I might forgot to mention that when i run lspci in Dom0 it shows me the
"hided" usb device. Isnt it supposed to be hidden?


I have exactly the same problem.
