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.
Devices known to work with this driver include:
Creative Tech NOMAD MuVo TX
FujiFilm FinePix1300 Digital Camera
IOmega Zip 100
IOmega Zip 250
Kingston DataTraveler 2.0
LaCie CD R/W
Lexar Media JumpDrive Flash Disks
Neodio Multi-format Flash Controller
Olympus C-5050 ZOOM Digital Camera
SanDisk ImageMate SDDR-31
Siemens MP3-Player USB
Sony DSC Digital Cameras
STMicroelectronics ST92163 Mass Storage library Tester
Y-E Data FlashBuster floppy
atapi(4), scsi(4), usb(4), wd(4)
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.
