So here is the patch.
Use USB vendor and product IDs to determine whether the attached
device is a CDROM or a Flash device. Daniel Drake says that the
*same* vendor and product IDs for non-HP vendor ID could be either
flash or cdrom, so try to probe for them (I think that the probe may
not work; it doesn't work properly now, which is why I'm writing this
patch).
