BYD trackpad detected as PS/2 mouse

Hi!
Automatic detection of BYD touchpads was sadly disabled at the end of
last year. They can be still be used by forcing the protocol manually as
described by Kai-Heng Feng above.
The reason for disabling detection was that the detection code generated
false positives with normal PS/2 mice
What detection was disabled and what was the good reason?

Actually the factory is TopStar China and the model is U731.
As detection was disabled for good reason, the bast would be to have
some config files to force detection only on machines where the user
know that he needs this driver

Yep - I changed the bug status to "Fix committed" which I think makes

Expected to be able to use as touchpad
Ok, so I've managed to write a kernel driver, as an extension to
psmouse, which recognises the touchpad and puts it into gesture-enabled
mode. Currently it recognises and uses vertical and horizontal two
finger scrolling, and also knows about the other gestures (but I haven't
got around to
*previous comment continued.
Gesture recognition is done by the touchpad and not the driver, and it's
not very good. I.e., it reports the gesture, not the finger positions,
so we can't configure things like scroll threshold.
The way to improve this would be to somehow put it in 'absolute' mode,
