The options are as follows:
|
|
.Bl -tag -width " "
|
|
.It Fl u Ar unit
|
|
Limit device range to USB devices connected to the given USBUS 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 Fl d Ar [ugen]<unit>.<addr>
|
|
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 "ugen".
|
|
.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 h
|

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.
