.Sh DESCRIPTION
|
|
.Nm
|
|
handles the USB device attachment and detachment. It does two things.
|
|
Through opening the
|
|
.Pa /dev/usb0 ,
|
|
.Pa /dev/usb1 ,
|
|
etc. devices, it enables the kernel to do handle change requests from
|
|
attached hubs. This functionality will be removed when the kernel has
|
|
kernel threads. The (multiple)
|
|
.Fl f Ar device
|
|
command line options specify which controllers it should handle.
|
|
Normally this option is not needed.
|
|
.Pp
|
|
The second part is the handling of the attachment and detachment of USB
|
|
devices. The device
|
|
.Pa /dev/usb
|
|
is opened and events are read from it. Whenever a device is attached or
|
|
detached the list of actions read from
|
|
.Pa /etc/usbd.conf
|
|
are searched for a matching entry. If found, the corresponding action is
|
|
executed.
|
|
.Pp
|
|
The command line options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl c Ar filename
|
|
Name of configuration file. The default is
|
|
.Pa /etc/usbd.conf.
|
|
.It Fl d
|
|
Enable debugging to the standard output,
|
|
and do not disassociate from the controlling terminal.
|
|
.It Fl e
|
|
Do one device tree exploration, no event queue handling and then exit.
|
|
.It Fl f Ar device
|
|
Specify the pathname of a USB controller device file.
|
|
The flag may be repeated to watch more than one USB controller.
|
|
The default is
|
|
.Pa /dev/usb0
|
|
through
|
|
.Pa /dev/usb3 .
|
|
Do not specify the device
|
|
.Pa /dev/usb
|
|
here. It is used for events only.
|
|
.It Fl n
|
|
Do not handle the event queue on /dev/usb.
|
|
.It Fl t Ar timeout
|
|
Set the timeout interval (in seconds) before an exploration happens
|
|
without being triggered by a connect or disconnect.
|
|
A timeout of 0 means that there is no timeout. The default is 30.
|
|
.It Fl v
|
|
Be verbose. Repeating the flag makes
|
|
.Nm usbd
|
|
more verbose.
