Synaptics touchpad hidden in a keyboard

Synaptics touchpad hidden in a keyboard

Hey folks, this is my first posting to a kernel list (that I can
remember :), so my apologies if I do anything silly. I've skimmed the
FAQ though, so hopefully...

I'm not sure if this is the right place to send this either, so if there's
somewhere else I should be sending to, please let me know.

So I've gotten an "iOne Scorpius R31" [1], which is really a Qtronix device.
It has an embedded Synaptics touchpad which isn't recognized by the kernel
[2]. If it's even possible for it to be recognized anyways (it looks like
psmouse-base.c (psmouse_extensions) and synaptics.c (synaptics_detect)
actually try to communicate with the device using the appropriate protocol,
so maybe there's no hope).

I've attached the relevant sections of 'lsusb -vvv' and the file
/proc/bus/input/devices, as well as a highly-compressed, low-resolution
picture of the back of the touchpad itself [3] (which clearly shows
"Synaptics" on it, incidentally). I'm suspecting that the controller in the
keyboard hides the touchpad.

Anyhoo, if there's anything I can do to help get it recognized, please let
me know.

Thanks in advance,

Dave

Something I had neglected to mention; 'tpconfig -i' does at least
partially recognize it:

        [ dbharris@willow: ~/ ]$ sudo tpconfig -i
        Found Synaptics Touchpad.
        Firmware: 8.96 (multiple-byte mode).
        Sensor type: unknown (0).
        Geometry: rectangular/landscape/up.
        Packets: absolute, 80 packets per second.
        Corner taps disabled;           no tap gestures.
        Edge motion: none.
        Z threshold: 6 of 7.
        2 button mode; corner tap is right button click.
        [ dbharris@willow: ~/ ]$ 

Thanks again,

Dave
