1763 * Please note that for multitouch devices (driven by hid-multitouch driver),
1764 * there is a proper autodetection and autoloading in place (based on presence
1765 * of HID_DG_CONTACTID), so those devices don't need to be added to this list,
1766 * as we are doing the right thing in hid_scan_usage().
1767 *
1768 * Autodetection for (USB) HID sensor hubs exists too. If a collection of type
1769 * physical is found inside a usage page of type sensor, hid-sensor-hub will be
1770 * used as a driver. See hid_scan_report().
