I have cross-compiled the latest commit of tslib from github ( https://github.com/kergoth/tslib/commits/master ). My touchscreen is hooked up to my embedded board and I enabled the drivers from the vendor. When I boot and look at the output of 'cat /dev/input/touchscreen' I can see plenty of output being generated from moving my fingers around the screen. The Kernel also outputs to the console nicely formatted messages for 'finger1' and 'finger2'.

I am not able to calibrate however. When I set my environment variables like shown below and run ts_calibrate, it spits out the message 'xres = 640, yres = 480 tslib: Selected device is not a touchscreen (must support ABS and KEY event types)' and does nothing more...

So Linux knows that my device exists and I can see scrolling output, but tslib can't calibrate. What am I doing wrong and how can I fix this?
