Hey guys, I am trying to figure out why this touchscreen is not working. I am attempting to run ts_calibrate which (on my kernel) can be found @ usr/bin When I run the script:
root:/usr/bin# ts_calibrate
xres = 1920, yres = 1080
tslib: Selected device is not a touchscreen (must support ABS and KEY event types)
Took 2 samples...

Calibration constants: -62842 -100359 777 1470 28726 -222 65536
I am assuming I need to provide an argument so I am trying to figure out what the ts would be called. I check out /dev/input:
root:/dev/input# ls
by-path event0 event1 mice
It's not showing up here unless its event0 or event1 any idea what the problem might be. The ts is plugged in via a usb cable. Is there somewhere in the kernel I can probe to find out if the board is recognizing the ts?
EDIT: I tried:
root:/usr/bin# lsusb
Bus 001 Device 002: ID 0424:2514
Bus 001 Device 001: ID 1d6b:0002
root:/usr/bin# ts_calibrate 1d6b:0002

EDIT: So a little detail. I had a working ts and it broke (still works but screen is cracked) oredered a replacement. Plug that replacement in and it while it does show the application you can't interact with it. An lsusb with the old device plugged it shows three usb devices:
root@ccimx6qpsbc:/# lsusb
Bus 001 Device 003: ID 2808:81c9
Bus 001 Device 002: ID 0424:2514
Bus 001 Device 001: ID 1d6b:0002
and if you look above you will see that an lsusb with the new device only shows two. Perhaps this is a usb issue? Is there a usb configuration script I need to run perhaps?
