.Nd supervise USB attach/detach
.Sh SYNOPSIS
.Nm
.Op Fl d
.Op Fl f Ar device
.Op Fl t Ar timeout
.Op Fl v
.Sh DESCRIPTION
.Nm
handles the USB device attachment and detachment.
.Pp
The options are as follows:
.Bl -tag -width Ds
.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 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 ,
.Pa /dev/usb1 ,
.Pa /dev/usb2 ,
and
.Pa /dev/usb3 .
.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.
.El
