18 /* List of quirky USB devices. Please keep this list ordered by:
23 * as we want specific devices to be overridden first, and only after that, any
24 * class specific quirks.
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...
