Hi Flavien !

I have a laptop with a usual "synaptics" touchpad and a USB 8-button 
logitech mouse (MX500). It is working great for me with suspend-to-disk 
(implementation from www.suspend2.net, but I assume it should work with 
the mainline kernel too). The touchpad and the mouse work at the same 
time, the touchpad is declared as the CorePointer, and the usb mouse 
automatically works when I plug it, or if it is plugged when I resume 
from suspended state. Well, not all buttons work because I use the 
regular mouse driver which doesn't handle all of them.

My hibernate script unloads usb modules at suspend time, and they are 
loaded back at resume time (I assume it is udev which loads them).
As far as evdev is concerned, you won't see it in xorg.conf, but it is 
used, at least by the synaptics touchpad.

I hope this will help !

Best regards,

Timothée Lecomte
