[Xen-users] can't passthrough usb devices to domU (Unexpected error: <class 'xen.util.vusb_util.UsbDeviceParseError'>)


I try to passthrough an usb 1.1 device (floppy drive) to a domU.
Dom0 and domU are based on opensuse11.4.

I did the follwowing in dom0 

xenserver:~ # xm usb-list-assignable-devices

3-2          : ID 0644:0000 TEAC     TEAC FD-05PUB   
xenserver:~ # xm usb-hc-create vdrserver 1 2
xenserver:~ # xm usb-list vdrserver
Idx BE  state usb-ver  BE-path
