We (team) have tried Xen-3.4 stable and current unstable-dev branch on
number of Desktops. We have observed that on many desktops we can't
access keyboard (USB/Serial) and mouse after complete boot.

Further changing/adding config options we found that enabling
INPUT_EVDEV, makes work everything.
I am not sure about problem, but how about adding CONFIG_INPUT_EVDEV
as "default y".  (i have attached the patch also)

          Say Y here if you want your input device events be accessible
          under char device 13:64+ - /dev/input/eventX in a generic way.
