    Samsung has just released a portable USB3 SSD, coming in a very small
    and nice form factor. It's USB ID is 04e8:8001, which unfortunately is
    already used by the Palm Visor driver for the Samsung I330 phone cradle.
    Having pl2303 or visor pick up this device ID results in conflicts with
    the usb-storage driver, which handles the newly released portable USB3
    SSD.
    
    To work around this conflict, I've dug up a mailing list post [1] from a
    long time ago, in which a user posts the full USB descriptor
    information. The most specific value in this appears to be the interface
    class, which has value 255 (0xff). Since usb-storage requires an
    interface class of 0x8, I believe it's correct to disambiguate the two
    devices by matching on 0xff inside visor.
