[Bug 1424293] Re: BYD trackpad detected as PS/2 mouse
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 figuring out how they work with the input framework yet).
Check it out here:
$ git clone -b byd https://www.github.com/chrisdiamand/linux.git
The protocol is pretty simple - there's some ps2 init stuff, then a
sequence of magic bytes which I intercepted from the windows driver. It
returns 4 byte packets using the intellimouse protocol, except the last
bit (scroll/Z) takes different values depending on the gesture.
Some issues remain though:
- It's not supported in xf86-input-synaptics yet. This means you can't control parameters with synclient. I think things like intertial scrolling are handled here too.
- Gesture recognition seems to be being done by the touchpad itself
(firmware?) and not by the driver in the windows driver. Unfortunately
it doesn't do a very good job of it.

Bug description:
Hi, The exact device is this: http://bydit.com/doce/products/microelectronics/2474.html
Let me know if there is any further information you need that could help.
Expected to be able to use as touchpad with two finger
vertical/horizontal scrolling. Currently only able to use plainly.
