    USB: ftdi_sio: add support for FT-X series devices · dc0827c1
    Jim Paris authored
    Add PID 0x6015, corresponding to the new series of FT-X chips
    (FT220XD, FT201X, FT220X, FT221X, FT230X, FT231X, FT240X).  They all
    appear as serial devices, and seem indistinguishable except for the
    default product string stored in their EEPROM.  The baudrate
    generation matches FT232RL devices.
    
    Tested with a FT201X and FT230X at various baudrates (100 - 3000000).
