wow...
Thanks for your work :) 

Yesterday I update -CURRENT on my lenovo z400 touch ( r296180),  after
suspend-resume I spotted that is my usb mouse didn't work (touchpad works as
before)
I had the feeling that I read something about hid_get_item: Number of
items(256) truncated to 255 on ML, so I'm here. 

What I do: 
laptop# webcamd -l
Available device(s):
....
webcamd [-d ugen0.2] -N Synaptics-Large-Touch-Screen-SYNAPTICS -S unknown -M 0
...
Show webcamd usage:
webcamd -h
laptop# webcamd  -N Synaptics-Large-Touch-Screen-SYNAPTICS -S unknown -M 0
Attached to ugen0.2[0]
Creating /dev/input/event0

after that I reconnect my mouse and 'it works' (c) 
How I can do this   automatically right?
