# Native support for HID input from the linux kernel¶

Support starts from 2.6.32-ubuntu, or 2.6.34.

[input]
# devicename = hidinput,/dev/input/eventXX
# example with Stantum MTP4.3" screen
stantum = hidinput,/dev/input/event2


Note

You can use a custom range for the X, Y and pressure values. For some drivers, the range reported is invalid. To fix that, you can add these options to the argument line:

• invert_x : 1 to invert X axis
• invert_y : 1 to invert Y axis
• min_position_x : X minimum
• max_position_x : X maximum
• min_position_y : Y minimum
• max_position_y : Y maximum
• min_pressure : pressure minimum
• max_pressure : pressure maximum
• rotation : rotate the input coordinate (0, 90, 180, 270)

For example, on the Asus T101M, the touchscreen reports a range from 0-4095 for the X and Y values, but the real values are in a range from 0-32768. To correct this, you can add the following to the configuration:

[input]
t101m = hidinput,/dev/input/event7,max_position_x=32768,max_position_y=32768


New in version 1.9.1: rotation configuration token added.
