[PATCH] USB: shuttle_usbat: Hardcode detection of HP CDRW devices

Browse Source 
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.
