In window's it works great using the GeneralTouch altered egalax drivers. I don't know what has been changed, but they have at least been rebranded. In ubuntu 9.0.4 it is detected by the synaptics driver and the mouse movement is great, except it treats it as a touchpad, not a touchscreen. Any way it can be used to handle absolute co-ords? The movement is great in ubuntu.
usbtouchscreen recognizes the device. usbhid does not, despite the device being being a usbhid compliant device.
input: General Touch Co. Ltd. General Touch USB Touchscreen as /class/input/input7
I had a similar device and it worked OK. If slid aroudn the screen too much, the mouse wouldn't follow until you clicked, but at least it was functional. This was using usbtouchscreen and the egalax xorg driver from eeti.com. The proprietary usbmodule (TKUSB) from eeti has the same results as usbtouchscreen.
I thought it was possible to use generic evdev kernel/X driver, but I the kernel doesn't detect the device.
for the egalax X driver to work, I have to specify the exact event in teh configuration or the calibration tool won't work. I had a similar device and used to be able to specify /dev/input/event* as the device and it would find the touchscreen, but that doesn't work anymore.
I can run the eeti calibration tool and it will calibrate, but the mouse still won't respond properly. If I move around in the very bottom left 10% of the screen, the TS generates some reasonable data and will move the mouse around (although won't move the mouse to my touch location). It looks like Y axis is reversed also. If you touch anywhere else on the screen, it moves the mouse to the far left of the screen and the mouse won't respond to sliding.
I'm running 2.6.30-gentoo-r6
