utility is used to configure and dump information about the USB subsystem.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width "-u unit"
|
|
.It Fl a Ar addr
|
|
Limit device range to the given USB device index.
|
|
Should only be used in conjunction with the unit argument.
|
|
.It Xo

.Fl d
|
|
.Sm off
|
|
.Oo Oo Cm /dev/ Oc Cm ugen Oc Ar unit Cm \&. Ar addr
|
|
.Sm on
|
|
.Xc
|
|
Limit device range to USB devices connected to the given unit and address.
|
|
The unit and address coordinates may be prefixed by the lowercased word
|
|
.Cm ugen ,
|
|
or the full path name
|
|
.Cm /dev/ugen .
|
|
.It Fl h
|
|
Show help and available commands.
|
|
.It Fl i Ar interface_index
|
|
Specify interface index as indicated by the command description.
|
|
If this argument is not specified
|
|
a value of zero will be used for the interface index.
|
|
.It Fl u Ar unit
|
|
Limit device range to USB devices connected to the given USBUS unit.
|
|
.It Fl v
|
|
Activate the
|
|
.Cm dump_device_desc ,
|
|
.Cm dump_curr_config_desc ,
|
|
and
|
|
.Cm show_ifdrv
|
|

|
|
.Pq Dq verbose mode .

.Pp
|
|
The following commands may be used with

Choose the configuration for the USB device.
|
|
Valid values range from zero to the number reported as the
|
|
.Ar bNumConfigurations
|
|
in
|
|
.Cm dump_device_desc
|
|
output.
|
|
The special value of 255 unconfigures the device, detaching
|
|
the interface drivers and reducing the power consumption to minimum,
|
|
but without going into power saving mode or detaching from the bus.
|
|
In some cases, it prevents the device from charging.
|
|
.It Cm set_alt Ar alt_index
