I have run BT4 in my Asus eee 1000h, and touchpad dont work. I have to plug an usb mouse to use.
In BT3, touchpad works fine (i use BT3 actually in this laptop)
And (isnt a new topic), rt2860 doesnt work. I think that (with actual drivers) it can be used in Mode Monitor, but inyection isnt supported yet.
Its my first message, nice to meet you ;-)
EDIT: All of them with BT4 LiveUSB
