An alternative would be to change subclass 02h to say MMC-2 and above...

Members:
Curtis Stevens (Western Digital) came to our MMC WG meeting on 19 September
2007 to bring up a concern about UBC mass storage bridge implementations.
The drive sub-class may be specified as either
SFF8020/MMC-2 (value = 2) or Transparent SCSI (value=6). Since SFF8020 is
obsolete and MMC-2 has been withdrawn as a standard, we should act to
promote the use of only drive sub-type 6. Keiji Katata (Pioneer) proposed
that drive sub-type 2 be made obsolete. If you are aware of common use of
drive sub-type 2, please respond to this message.
Kind Regards,
Bill McFerrin
