Re: [Xen-users] xm usb-add syntax

[Brian Krusic <brian@xxxxxxxxxx>]

Hi Dieter and thanks.

I found some docs explaining that on my guest VM, I should run  
"modprobe xen-hcd" which returns;
FATAL: Module xen_hcd not found.

The kernel on this PVM is 2.6.18-53.

At any rate, after I run the command;

xm usb-attach domU 0 1  2-4

I get this;

Unexpected error: xen.util.vusb_util.UsbDeviceParseError

Please report to xen-devel@xxxxxxxxxxxxxxxxxxx
Traceback (most recent call last):

bus)
xen.util.vusb_util.UsbDeviceParseError: vusb: Error parsing USB device  
info: Can't get assignment status: (2-7).

Should I post this to xen-devel?
