There is no Wacom kernel driver for the Wacom serial ISD version 4 device you are using. Everything is in the Wacom X driver. > IMHO, the best support for this driver would be as a > kernel module that could use the input subsystem to send multitouch > events up through the evdev interface. Sure, you can add yours and a bunch of the other serial WACfxxx devices into the kernel under input/touchscreen (I believe Jaya Kumar <jayakumar.lkml@xxxxxxxxx> has added the pen-only one there already). But you would need to update the Wacom X driver as well. Without the proper X driver to work with it, kernel driver is pretty much useless. Or you may be able to let X evdev driver take care of it as a generic touch screen device. I don't know how good the X evdev driver handles the touch events though. > Do you have any information on this device? What kind of information do you need?

I do not have time to work on it. That is the reality.
