HID service "hid:SPVR"
This is used by Home Menu and other system titles. The command-handler for this is the same as the other HID services, see above.
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. This cmd-handler thread only runs on core2-3, while the other cmd-handler threads run on core0. The cores the cmd-handler thread runs on is the only difference between hid:QTM and the other HID services.
