Anyway, please try the driver (you may need to hardcode the IRQ

type for now) and see if psmouse is able to talk to the touchpad.
If it
is then serio is the proper solution.
Dmitri,
I fixed one line in the wpce775x_serio driver which looked like a
typo - hope I got that right:
for (i = 0; i < count; i++)
- serio_interrupt(ps2if->serio, ps2if->data_in[1], 0);
+ serio_interrupt(ps2if->serio, ps2if->data_in[i], 0);
}
Yep, that was a typo.
I tried running with psmouse but it didn't work. The touchpad was
never detected as a synaptics touchpad. I looked at the dataflow
from the device and it wasn't responding to the commands that
synaptics_detect() was sending it. It eventually showed up as an
unknown logitech mouse.
That suggests that the device responds to at least basic PS/2 queries.
I can see data being passed through the serio driver but the
logitech driver can't process it.
What about loading psmouse module with proto=bare?
Could you also dump the data received from touchpad during probing?
