Hi,
I'd run a config which use my whole usb card in domu on debian xen on etch
(3.0.3).
My NEC Usb and my ALi USB has claimed more than one pci devices. Here a
tree of mypcidevices with ali:

I'd trouble by pass only one of them to the domu so could you check
first, that you will export all your pci-devices of the usb-card?
Which xen-version is used in domu please?
Is it an hvm domu? Im not shure but I mean exporting pci-devices to an
hvm dom is not working, yet.
Could you give me a pcilist -tv to see your device tree, please?
Do you have checked, that the device is really claimed by the pciback?
Check with ls -l /sys/bus/pci/devices/0000\:00\:1d.7. Here is an example:
xen:/etc/xen# ls -l /sys/bus/pci/devices/0000\:02\:00.1/driver|less
lrwxrwxrwx 1 root root 0 2007-10-17 13:17 /sys/bus/pci/devices/0000:02:00.1/\
driver -> ../../../../bus/pci/drivers/pciback
And last question: Which guest kernel you are using?
MfG...
