[Xen-devel] PVUSB not working on squeeze

[chris <tknchris@xxxxxxxxx>]

Hello,,

I am trying to use PVUSB on a debian squeeze dom0 as well as a squeeze domU. The error suggested I email here, so here it is. I do the following

root@dom0:~# xm usb-hc-create vm-test 2 16

root@dom0:~# xm usb-list-assignable-devices

1-7          : ID 17e9:0136 DisplayLink DL-195 Adapter

root@dom0:~# xm usb-attach vm-test 0 1 1-7

Unexpected error: <class 'xen.util.vusb_util.UsbDeviceParseError'>

Please report to xen-devel@xxxxxxxxxxxxxxxxxxx

Traceback (most recent call last):

  File "/usr/lib/xen-4.0/bin/xm", line 8, in <module>

    main.main(sys.argv)

  File "/usr/lib/xen-4.0/lib/python/xen/xm/main.py", line 3620, in main

    _, rc = _run_cmd(cmd, cmd_name, args)

  File "/usr/lib/xen-4.0/lib/python/xen/xm/main.py", line 3644, in _run_cmd

    return True, cmd(args)

    raise UsbDeviceParseError("Can't get assignment status: (%s)." % bus)

xen.util.vusb_util.UsbDeviceParseError: vusb: Error parsing USB device info: Can't get assignment status: (1-7).

root@dom0:~# uname -a

Linux dom0 2.6.32-5-xen-amd64 #1 SMP Tue Jun 14 12:46:30 UTC 2011 x86_64 GNU/Linux

One thing I noticed is that I don't see any kind of usbfront module or any usb frontend in lsmod. Is there some backend/frontend lacking in the squeeze kernel?

Any help would be greatly appreciated.
