|
||||
.Os
|
||||
.Sh NAME
|
||||
.Nm usbhidaction
|
||||
.Nd perform actions according to USB HID controls
|
||||
.Sh SYNOPSIS
|
||||
.Nm
|
||||
.Fl c Ar config-file
|
||||
.Op Fl d
|
||||
.Op Fl i
|
||||
.Fl f Ar device
|

|
||||
.Op Fl v

||||
.Ar arg ...
|
||||
.Sh DESCRIPTION
|
||||
.Nm
|
||||
can be used to execute commands when certain values appear on HID controls.
|
||||
The normal operation for this program is to read the configuration file
|
||||
and then become a daemon and execute commands as the HID items specify.
|
||||
If a read from the HID device fails the program dies; this will make it
|
||||
die when the USB device is unplugged.
|
||||
.Pp
|
||||
The options are as follows:
|
||||
.Bl -tag -width Ds
|
||||
.It Fl c Ar config-file
|
||||
Specify a path name for the config file.
|
||||
.It Fl d
|
||||
Toggle the daemon flag.
|
||||
.It Fl i
|
||||
Ignore HID items in the config file that does not exist in the device.
|
||||
.It Fl f Ar device
|
||||
Specify a path name for the device to operate on.
|
||||
If
|
||||
.Ar device
|
||||
is numeric, it is taken to be the USB HID device number.
|
||||
If it is a relative
|
||||
path, it is taken to be the name of the device under
|
||||
.Pa /dev .
|
||||
An absolute path is taken to be the literal device pathname.
|
||||
.It Fl p Ar pidfile
|
||||
Specify an alternate file in which to store the process ID.
|
||||
.It Fl v
|
||||
Be verbose, and do not become a daemon.
|
||||
.El
|
||||
.Pp
|
||||
The config file will be re-read if the process gets a HUP signal.
|
||||
.Sh CONFIGURATION
|
||||
The configuration file has a very simple format.
|
||||
Each line describes an
|
||||
action; if a line begins with a whitespace it is considered a continuation
|
||||
of the previous line.
|
||||
Lines beginning with `#' are considered as comments.
|
||||
.Pp
|
||||
Each line has three parts: a name of a USB HID item, a value for that item,
|
||||
and an action.
|
||||
There must be whitespace between the parts.
|
||||
.Pp
|
||||
The item names are similar to those used by
|
||||
.Xr usbhidctl 1 ,
|
||||
but each part must be prefixed by its page name.
|
||||
.Pp
|
||||
The value is simply a numeric value.
|
||||
When the item reports this value
|
||||
the action will be performed.
|
||||
If the value is `*' it will match any value.
|
||||
.Pp
|
||||
The action is a normal command that is executed with
|
||||
.Xr system 3 .
|
||||
Before it is executed some substitution will occur:
|
||||
`$n' will be replaced by the nth argument on the
|
||||
command line, `$V' will be replaced by the numeric value
|
||||
of the HID item, `$N' will be replaced by the name
|
||||
of the control, and `$H' will be replaced by the name
|
||||
of the HID device.
|
||||
.Sh FILES
|
||||
.Bl -tag -indent
|
||||
.It Pa /usr/share/misc/usb_hid_usages
|
||||
The HID usage table.
|
||||
.It Pa /var/run/usbaction.pid
|
||||
The default location of the pid file.
|
||||
.El
|
||||
.Sh EXAMPLES
|
||||
The following configuration file can be used to control a pair
|
||||
of Philips USB speakers with the HID controls on the speakers.
|
||||
.Bd -literal -offset indent
|
||||
# Configuration for various Philips USB speakers
|
||||
Consumer:Consumer_Control.Consumer:Volume_Up 1
|
||||
mixerctl -f $1 -n -w fea8-i7-master++
|
||||
Consumer:Consumer_Control.Consumer:Volume_Down 1
|
||||
mixerctl -f $1 -n -w fea8-i7-master--
|
||||
Consumer:Consumer_Control.Consumer:Mute 1
|
||||

|
||||
mixerctl -f $1 -n -w fea8-i7-bass--
