Hi,

I use Raspberry.
In syslog i have:
usb 1-1.4: Product: 3M USB Touchscreen - EX II
input: 3M 3M USB Touchscreen - EX II with /devices/platform/soc/3f980000.usb/usb1/1-1/1-1.4/1-1.4:1.0/input/input0

I tried to use touch screen but ex_touch_input.c says:
"Could not init touch input."

Some tips please.

Thanks.
