devb-umass

Driver for USB Mass Storage interface

In order to start this driver, you must be logged in as root, and the USB stack ( io-usb ) needs to be running.

Syntax:

devb-umass [blk option[,option]...]
           [cam option[,option]...]
           [disk option[,option]...]
           [umass options[,option]...]

Options:

Use commas (,) to separate the options. You can put the blk, cam, disk, and umass groups of options in any order.

blk options
The blk options control io-blk.so . If specified, they must follow the blk keyword. For more information, see io-blk.so.
cam options
The cam options control the common access methods:
quiet
Be quiet: don't display any information on startup.
verbose
Be verbose: display full information about units (devices) on startup.
pnp
Enable CAM plug and play (i.e. don't exit at startup when no devices are found). The default is off.
disk options
The disk options control the driver's interface to cam-disk.so . If specified, they must follow the disk keyword.
umass options
The umass options control the driver's interface to the USB device. If you've installed multiple devices, you can repeat these options for each device. Remember, however, to specify the umass keyword before each controller's set of options.
path=name
Connect to the specified USB stack. The default is /dev/io-usb/io-usb.
wait=num
Wait num of seconds for the USB stack. The default is 60 seconds.
vid=vid
The vendor ID of the device.
did=did
The device ID of the device.
busno=bus
The bus number of the USB controller.
devno=dev
The USB address of the device.
iface= if
The particular interface number of the device.
priority=prio
Set the priority of the processing thread. The default is 21.
ignore_csw
Ignore the Command Status Wrapper. Some devices return invalid data for the CSW.
