1493 * A list of devices for which there is a specialized driver on HID bus.
1494 *
1495 * Please note that for multitouch devices (driven by hid-multitouch driver),
1496 * there is a proper autodetection and autoloading in place (based on presence
1497 * of HID_DG_CONTACTID), so those devices don't need to be added to this list,
1498 * as we are doing the right thing in hid_scan_usage().

AH		 1499 *
1500 * Autodetection for (USB) HID sensor hubs exists too. If a collection of type
1501 * physical is found inside a usage page of type sensor, hid-sensor-hub will be
1502 * used as a driver. See hid_scan_report().
