 * There are many DisplayLink-based graphics products, all with unique PIDs.

 * So we match on DisplayLink's VID + Vendor-Defined Interface Class (0xff)

 * We also require a match on SubClass (0x00) and Protocol (0x00),

 * which is compatible with all known USB 2.0 era graphics chips and firmware,

 * but allows DisplayLink to increment those for any future incompatible chips
