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 hard-
     ware is very rare, and the support very likely no longer works after ATA
     subsystem redesign to support NCQ on October 7, 2017.

NetBSD 8.0                     October 23, 2018                     NetBSD 8.0
