It is hard to know which physical device +"hiddev0" represents, but on my Surface Pro 2 it is the Type Cover v2. You may +need to test hiddev1, hiddev2, etc. + +The utility will print the name of the device (so for a Type/Touch Cover 1/2 it +should be "MICROSOFT SAM"), and then enable or disable PTP mode as requested. + +Current Linux versions can't work when the touchpad is configured in PTP mode. +So in most scenarios you want to disable PTP mode. + +As an additional feature the tool will start listening and dumping events from +the selected device. Stop with Ctrl+C. |
