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... | |
