I don't see how that could happen. We have this code in
slave_configure():
/* Disk-type devices use MODE SENSE(6) if the protocol
* (SubClass) is Transparent SCSI, otherwise they use
* MODE SENSE(10). */
if (us->subclass != US_SC_SCSI)
sdev->use_10_for_ms = 1;
That's supposed to tell the SCSI core to use MODE SENSE(10) commands
(0x5a) rather than MODE SENSE(6) (0x1a).
