HID service "hid:QTM"
This was added with 9.0.0-20. HID module only registers+handles this service when running on New 3DS. The command-handler for this is the same as the other HID services, see above.

The cores the cmd-handler thread runs on is the only difference between hid:QTM and the other HID services.
