Re: [Xen-users] Xen-4 PVUSB kernel bug

[orstig <orstig@xxxxxxxxx>]

Hello, i have a similar problem with a logitech wireless mouse and keyboard
(all hardware i have tryied starting today), i use this line in domU.cfg
vusb = ['usbver=1, numports=2, port_1=1-2.4']

everything looks fine after boot up (device shows when lsusb and modules are
being loaded) but neither keyboard or mouse are working.

my crash (dom0) comes first when halting or rebooting domU

system: Ubuntu 10.04 server amd64, Xen 4.0, xen-sources-2.6.32-1 patches on
linux-2.6.32.10
hardware: Intel quad core 8GB RAM

hope someone have a solution /orstig
