Mousedev should provide a reasonable emulation of standard mouse giving user chance to configure the system properly. There is no need to task the driver to provide such emulation and therefore I will not apply this patch. > This patch > provides a default compatibility configuration, which works as a multi-button mouse, > implemented using rudimentary multi-finger options.

This happens automatically with Synaptics hardware on newer distributions (at least Fedora 9 does this). As far as I know SYnaptics driver does no look for specific product but for a certain features of the input device and so shoudl work for BCM as well. > > * Two-finger scroll emulates a mouse wheel. > > * Three-finger swipe emulates a horizontal mouse wheel. > > * Multi-finger clicks emulate the middle and right mouse buttons. > The kenel driver should only do as little translation as possible, allowing userspace to decide how to implement more fancy features. > * The mouse driver also works with gpm in text consoles, providing cut-and-paste functionality. > Does not mousedev emulation work from GPM? Also GPM has evdev protocol support which should work very well with synaptics-like touchpads. -- Dmitry -- To unsubscribe from this list: send the line "unsubscribe linux-input" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
