The umass
driver provides support for USB mass storage
class devices. The driver supports subclasses SCSI, 8020i (ATAPI), 8070i
(ATAPI), QIC157 (ATAPI), RBC (subset of SCSI), and UFI (USB Floppy). The
driver handles the protocols Bulk-Only, CBI, and CBI-with-CCI.

The umass
driver is a port of the
FreeBSD driver. The umass
driver appeared in NetBSD 1.5.
The driver has some support for certain adapters from In-System Design that use
the (non-standardized) ATA protocol over Bulk-Only. This hardware is very
rare, and the support very likely no longer works after ATA subsystem redesign
to support NCQ on October 7, 2017.
