.Os FreeBSD
|
|
.Sh NAME
|
|
.Nm usbd.conf
|
|
.Nd
|
|
.Xr usbd 8
|
|
configuration file
|
|
.Sh DESCRIPTION
|
|
The
|
|
.Nm
|
|
file is the configuration file for the
|
|
.Xr usbd 8
|
|
daemon.
|
|
It provides information to allow execution of userland commands
|
|
on events reported by the
|
|
.Xr usb 4
|
|
subsystem in the kernel.
|
|
Currently the only events are device attach and
|
|
detach, but could in the future be extended to include power management
|
|
functions.
|
|
.Pp
|
|
The configuration file consists of a sorted list of entries.
|
|
Each entry
|
|
describes a set of criteria commands.
|
|
When an event occurs, the criteria
|
|
are checked and if met, the commands for that event are executed through
|
|
a shell.
|
|
The list is sorted and scanned from top to bottom.
|
|
The first
|
|
matching entry is used for an event.
|
|
.Pp
|
|
Each entry contains a number of fields.
|
|
There are 3 types of fields:
|
|
descriptive fields, selection criteria and commands to execute on
|
|
events.
|
|
The field name is case sensitive and should be all lower case.
|
|
Each field can have one or more arguments.
|
|
.Pp
|
|
The following fields are available:
|
|
.Bl -tag -width devicename\ <Id>
|
|
.It device Ar string
|
|
Start a new entry.
|
|
.Ar string
|
|
is an arbitrary string used for pretty printing.
|
|
.It product Ar id
|
|
Product Id
|
|
.It vendor Ar id
|
|
Vendor Id
|
|
.It release Ar id
|
|
Release Id, also called revision Id sometimes.
|
|
.It class Ar id
|
|
Device Class
|
|
.It subclass Ar id
|
|
Device Subclass
|
|
.It protocol Ar id
|
|
Device Protocol
|
|
.It devname Ar string
|
|
Device name, for example umass2, or ums0. These device names can contain
|
|
regular expressions.
|
|
See
|
|
.Xr regex 3
|
|
and
|
|
.Xr re_format 7 .
|
|
The device name that is matched can be used in the commands below
|
|
through adding ${DEVNAME} somewhere in that string.
|
|
.El
|
|
.Pp
|
|
String arguments may be quoted.
|
|
If a string argument contains a space or
|
|
tab character it needs to be enclosed in single or double quotes.
|
|
If an
|
|
argument contains a single or double quote, that quote needs to be
|
|
enclosed in double or single quotes respectively.
|
|
See below for
|
|
examples.
|
|
.Pp
|
|
Numeric arguments can either be specified in decimal (42), octal (052) or
|
|
hexadeximal (0x2a).
|
|
.Pp
|
|
The values for the fields
|
|
.Li product , vendor , release, class , subclass
|
|
and
|
|
.Li protocol
|
|
can be retrieved by killing the
|
|
.Nm usbd
|
|
daemon and running it with the
|
|
.Fl d
|
|
and
|
|
.Fl v
|
|
flags.
|
|
.Pp
|
|
Commands to be executed when the action is matched:
|
|
.Bl -tag -width devicename\ <Id>
|
|
.It attach Ar string
|
|
Shell command to execute when a device is attached.
|
|
.It detach Ar string
|
|
Shell command to execute when a device is detached.
|
|
