* A list of devices for which there is a specialized driver on HID bus.

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