19 * 1) Vendor ID
20 * 2) Product ID
21 * 3) Class ID
22 *
23 * as we want specific devices to be overridden first, and only after that, any
24 * class specific quirks.
25 *
26 * Right now the logic aborts if it finds a valid device in the table, we might
27 * want to change that in the future if it turns out that a whole class of
28 * devices is broken...
