DESCRIPTION
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.

HISTORY
The umass driver is a port of the
FreeBSD driver. The umass
driver appeared in NetBSD 1.5.
NOTES
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.
