.Dt USBD.CONF 5
.Os
.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 ${DEVNAME} somewhere in that string.
.El
.Pp
String arguments may be quoted.
If a string argument contains a space or
tab character it needs to be enclosed in single or double quotes.
If an
argument contains a single or double quote, that quote needs to be
enclosed in double or single quotes respectively.
See below for
examples.
.Pp
Numeric arguments can either be specified in decimal (42), octal (052) or
hexadeximal (0x2a).
.Pp
The values for the fields
.Li product , vendor , release, class , subclass
and
.Li protocol
can be retrieved by killing the
.Nm usbd
daemon and running it with the
.Fl d
and
.Fl v
flags.
.Pp
Commands to be executed when the action is matched:
.Bl -tag -width devicename\ <Id>
.It attach Ar string
Shell command to execute when a device is attached.
.It detach Ar string
Shell command to execute when a device is detached.
.El
.Sh EXAMPLES
A sample entry to rescan the SCSI bus on connection of a
.Tn "Iomega USB Zip Drive" :
.Bd -literal
device "USB Zip drive"
product 0x0001
vendor 0x059b
release 0x0100
attach "/usr/bin/camcontrol rescan bus 0"
.Ed
.Pp
To start up moused for a newly attached mouse:
.Bd -literal
device "Mouse"
devname "ums[0-9]+"
attach "/usr/sbin/moused -p /dev/${DEVNAME} -I /var/run/moused.${DEVNAME}.pid"
.Ed
.Sh FILES
.Bl -tag -width /etc/pccard.conf -compact
.It Pa /etc/usbd.conf
The
.Nm usbd
configuration file.

.Sh SEE ALSO
.Xr usb 4 ,
.Xr usbd 8 ,
.Xr usbdevs 8
.Sh BUGS
It is currently not possible to use a selection criterium more than once. For
example it is not possible to specify more than one vendor Id.
