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 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 9.0 October 23, 2018 NetBSD 9.0
