loop until all data read:

The vendor specific command 0x09 and 0x0e are issued by the windows driver to the AVEC 2400, but the scanner rejects them.

The Dextra DF600-P is a VM3510. It's older than the other scanner and
is a little more primitive. The driver recognizes its scsi id and fake
a more evolved one. The scan sequence is also simplified. The rest is
identical.
