mtrack: cannot open device #20

Closed gzm55 closed 6 years ago

OS: Ubuntu 18.04 Kernel: 4.15

After install the driver and the mtrack config, my trackpad2 can't be loaded, with the error Cannot open device /dev/input/event* Permission denied. I have tested usb and bt, the error log is the same.

Full log:
