/* ts A91205
LG GH22LS30 revision 1.00 returns for DVD-R format
code 0x0E an allocation length of 4 (= 0 payload).
A MS-Windows tool can inquire media code "RITEKF1",
though.
This macro causes a try to unconditionally read the
desired payload bytes. The drive then returns 35
bytes as requested and the media id is "RITEKF1".
Nevertheless this is not a generally usable gesture
because older Linux USB dislikes requests to fetch
more bytes than the drive will deliver.
