The cursor is very quick in most apps but it a bit erratic in duke3d and quake. Quake worked perfectly, i mean perfectly!, for a while then only allowed up down aiming and ignored left-right movement. duke3d was opposite it responded great to left-right but not up-down. Mouse buttons worked in quake but only scroll button worked in duke.

I notice a extra drain on battery life even though i'm using a powered hub. is there a way to prevent the n800 from giving power to the mouse?

still really awesome! you should submit the deb to maemo.org so that more people realize it works.
