/* List of quirky USB devices.  Please keep this list ordered by:
 * 	1) Vendor ID
 * 	2) Product ID
 * 	3) Class ID
 *
 * as we want specific devices to be overridden first, and only after that, any
 * class specific quirks.
 *
 * Right now the logic aborts if it finds a valid device in the table, we might
 * want to change that in the future if it turns out that a whole class of
 * devices is broken...
