Hi Chris,

1) It uses the MT slot protocol
2) It creates two input devices, but only one is useful

No biggy to userspace.  I'm assuming for unused input device that
hardware is still reporting a HID_USAGE_STYLUS and probably you could
catch that and not register that input device.

The initial idea was to only use the trackpad usb endnode, but the device does
not work at all after boot unless the silent endnode is somehow taken into
account. I am not sure what your statement refers to.

3) It works well with the synaptics and multitouch X drivers
4) It does not work well with the wacom X driver (!)

Once we finalize input events sent, I'm sure we could get
xf86-input-wacom to play nice with this synaptic-style input events.
The harder part is to develop userspace rules to assign this "wacom"
input device to something other than xf86-input-wacom; especially in
case were tablet has pen and touch input devices.

Using udev rules, the pen device is picked up by the wacom X driver and the
touch device is picked up by the synaptics X driver. It does not seem anything
extra is needed here.

You mean your wacom touch device are being directed to synaptics X
driver without modifications to udev or similar rules?  On my
unmodified Fedora box, they both go to wacom X driver.

Not that it would be a difficult modification... I'd just need to make
those and work with distributions to also align.

50-wacom.conf sorts after 50-synaptics.conf and since we apply the wacom
driver to anything with Wacom in the product name, it overrides the
synaptics setting. not a big deal at all, just renaming it to 40-wacom.conf
should already do the job.

Cheers,

Thanks for tip.  I verified its that easy.  I renamed to 40-wacom.conf
and on my Bamboo Pen&Touch, the tablet part is grabbed by
xf86-input-wacom and the touchpad part is grabbed by
xf86-input-synaptics.

Note I have the linuxwacom (out-of-tree) driver installed which makes
my Bamboo talk like the in-tree wacom Tablet PC logic.  And in this
case, I get no responses from the Bamboo touchpad and
xf86-input-synaptics combo.

I mention this because udev is reporting Tablet PC as a touchpad.  So
if we change to allow remapping Bamboo's to xf86-input-synaptics then
we either need to update Tablet PC logic to be synaptics-like in
kernel or we need an exception to allow older Tablet PC to continue to
be handled by xf86-input-wacom.
