Problem with usb toichscrenn...
 
Hello,

I have a Geode with 2.6.24.7 with preempt-rt. In usb port I have connected a usb touchscreen device but linux did not recognize touchscreen properly.
I have supposed that Linux recognize touchscreen device as /dev/input/tsx, but when kernel boot, it recognize as /dev/input/mouse0 or input1.

The problem is that TSLIB do not undertand this device, because TSLIB think that mouseX is not touchscreen device.

My question is, how can I configurate my kernel to recognize my touchscreen usb as /dev/input/tsX???

Or better, Could somebody explain me what is the problem???
Best regards.

If all you're missing is that device, you could go a low-tech route for a solution, and create a symbolic link:

ln -s /dev/input/mouse0 /dev/input/tsx

And see if it works. If so, you could put something in a startup script, to create that link at boot-time.

Hello TBOne,

Good idea, but it does not work.

TSLIB return me the same output: " selected device is no a touchscreen device, I understand".

Well, I will try to find more information about TSLIB and why is the reason that TSLIB does not reconigze device as touchscreen.

Thank you very much.

Best regards
