RE: [Xen-users] Passing USB device to MS Windows guest

["Dustin Henning" <Dustin.Henning@xxxxxxxxxxx>]

        I believe I read on this list that the version of qemu that ships
with Xen only supports passing through one USB device and the tablet counts
(but I can't find the message).  That said, if you get rid of the tablet and
qemu will emulate a PS/2 mouse (not sure if it will or not), then you might
be able to pass one other USB device through with the commands you are
trying.  Short of that, you can refer to this thread:
http://lists.xensource.com/archives/html/xen-users/2007-06/msg00909.html
and try PCI passthrough or network USB.  Hopefully someone will correct me
if I am wrong or this has changed.  Good luck,
        Dustin

Subject: [Xen-users] Passing USB device to MS Windows guest

The configuration:

Dom0: openSuse 11.1 xen kernel for x86_64 and Xen 3.3.1
DomU: MS Windows XP

I want to pass a USB device with the identification 05e3:0100 to the DomU

First attempt:
I added a line
usbdevice="host:05e3:0100"
to the configuration file for the DomU already existing in /etc/vm. The file
also contains the lines
usb=1
usbdevice="tablet"
.

After rebooting the VM in DomU no USB device other than the "tablet" 
(mouse equivalent) is available.
A look at the log files of the Dom0 reveals no mention of "host:05e3:0100".

Second attempt:
On the graphical console (vnc) of the VM running Windows I switched to the
qemu monitor (version 0.9.1) with Alt+Crl+2 and entered the command
"usb_add", and qemu answered: "unknown command: 'usb_add'; by the way,
"help" doesn't list "usb_add" either.

So both approaches described in the Xen 3.3 User's Guide and in some other
places on the web don't work.

Since the only reason for running Windows is using a software package that
isn't available for Linux and that uses the USB device as input device, I'm
stuck and need urgently help.

Regards
Willy
