Xen users - Sep 2011 - How to PVUSB with xen-sources-2.6.34-r4 and xen-4.1.1 on gentoo

Hello,

I''ve installed xen-4.1.1 on with Gentoo xen-sources-2.6.34-r4 (both
dom0 and domU) on an AMD athlon XP 32 bits.
I PCI passthrugh the whole USB-2.0 controler to the domU to gain access to my
wifi dongle and everything works fine and stable.

However, I''ve got an USB drive that I want to use on my dom0 wich
requires USB-2.0 too and then cannot use anymore the PCI passthrugh method but
the PVUSB method.

Here is the problem, creating the virtual USB controler and attaching the dongle
to this controler works and in domU lsusb shows both the controler and the
dongle but as soon as I try to up the wlan device, dom0 crash.

Does anybody have any succes with PVUSB on PV domUs and how?
Any ideas on how I can make PVUSB work ?

Regards

Thank you for your answer, but that''s exactly the doc I''ve
followed.

In fact  I''ve digged a little more : my wifi dongle uses the RT73
driver which uses the serialmonkey RT73-firmware and when I plug the dongle,
I''ve got in the syslog :

[kernel] rt73usb 1-1:1.0: firmware: requesting rt73.bin
[kernel] phy0 -> rt2x00usb_vendor_request: Error - Vendor Request 0x07 failed
for offset 0x3040 with error -110.

Any ideas?
