However, if it was possible to forward commands to the external mouse, we could implement a full passthrough like synaptics.c has, and then support any kind of external mouse (including wheels, bells and whistles.) > I personally never used an external mouse.

That's probably because the quickpoint is connected in place of the external mouse. -- Vojtech Pavlik SuSE Labs, SuSE CR - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
