Wacom Intuos 4 on Haiku R1 Alpha 4.1

[Adriano Araújo Duarte]

Hi all!
I have a graphic tablet Wacom Intuos 4 (PTK440) and I'd love so much to see it working on Haiku.
My Haiku R1 Alpha 4.1 installation have the Wacom driver, but the tablet don't work.
My computer is an Acer Aspire One D250-1080.
These are the listusb and syslog messages:

Creating a ticket is always the best idea in such situations. After
checking none already exists, of course. :-)

Instead of crossposting to 2 lists...

I am the author of (most of the code of) the Wacom driver. The driver is
split into two parts. The first part is a kernel USB driver. That one
just looks for USB devices from the Wacom vendor and takes ownership. It
puts these devices into tablet mode with a special control command.
The second part of the driver is an input_server addon that connects to
the kernel driver. The problem here is that the support for specific
Wacom devices is built into the input_server addon and that it doesnt
actually support your Wacom device version.

It seems your device is just not listed in the driver as supported:
http://cgit.haiku-os.org/haiku/tree/src/add-ons/input_server/devices/wacom/TabletDevice.cpp#n111

I think there was some work done to make the general HID driver support
tablets, in a much more generic way than the Wacom driver does. I dont
know how much effort it would be to disable the Wacom driver from taking
ownership of the device and make the HID driver claim responsibility
instead. Maybe that would already be enough to make it work...

Unless the HID driver explicitly blacklists the wacom devices, removing
the wacom binary (moving it away) should get it picked up at least, no?

I think it does exactly that. I am also not sure how much tested the
support is. For example, for the driver to more usable, it should
implement a jitter filter, like the Wacom driver does. I am not aware
that such a thing had been done.

The driver sees a wacom device but doesn't know how to handle it so it
just bails out.

You'd need to add a case there for the calibration data and one for the
name.
