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