40: .Os
41: .Sh NAME
42: .Nm usbhidaction
43: .Nd perform actions according to USB HID controls
44: .Sh SYNOPSIS
45: .Nm
46: .Fl c Ar config-file
47: .Op Fl d
48: .Op Fl i
49: .Fl f Ar device
50: .Op Fl v
51: .Ar arg ...
52: .Sh DESCRIPTION
53: .Nm
54: can be used to execute commands when certain values appear on HID controls.
55: The normal operation for this program is to read the configuration file
56: and then become a daemon and execute commands as the HID items specify.
57: If a read from the HID device fails the program dies; this will make it
58: die when the USB device is unplugged.
59: .Pp
60: The options are as follows:
61: .Bl -tag -width Ds
62: .It Fl c Ar config-file
63: Specify a path name for the config file.
64: .It Fl d
65: Toggle the daemon flag.
66: .It Fl i
1.3 ! hugh 67: Ignore HID items in the config file that do not exist in the device.
1.1 nate 68: .It Fl f Ar device
69: Specify a path name for the device to operate on. If
70: .Ar device
71: is numeric, it is taken to be the USB HID device number. If it is a relative
72: path, it is taken to be the name of the device under
73: .Pa /dev .
74: An absolute path is taken to be the literal device pathname.
75: .It Fl v
76: Be verbose, and do not become a daemon.
77: .El
78: .Pp
79: The config file will be re-read if the process gets a HUP signal.
80: .Sh CONFIGURATION
81: The configuration file has a very simple format. Each line describes an
82: action; if a line begins with a whitespace it is considered a continuation
83: of the previous line. Lines beginning with `#' are considered as comments.
84: .Pp
85: Each line has three parts: a name of a USB HID item, a value for that item,
86: and an action. There must be whitespace between the parts.
87: .Pp
88: The item names are similar to those used by
89: .Xr usbhidctl 1 ,
90: but each part must be prefixed by its page name.
91: .Pp
92: The value is simply a numeric value. When the item reports this value
93: the action will be performed.
94: If the value is `*' it will match any value.
95: .Pp
96: The action is a normal command that is executed with
97: .Xr system 3 .
98: Before it is executed some substitution will occur:
99: `$n' will be replaced by the nth argument on the
100: command line, `$V' will be replaced by the numeric value
101: of the HID item, `$N' will be replaced by the name
102: of the control, and `$H' will be replaced by the name
103: of the HID device.
104: .Sh FILES
105: .Pa /usr/share/misc/usb_hid_usages
106: The HID usage table.
107: .Sh EXAMPLES
108: The following configuration file can be used to control a pair
109: of Philips USB speakers with the HID controls on the speakers.
110: .Bd -literal -offset indent
111: # Configuration for various Philips USB speakers
112: Consumer:Consumer_Control.Consumer:Volume_Up 1
113: mixerctl -f $1 -n -w fea8-i7-master++
114: Consumer:Consumer_Control.Consumer:Volume_Down 1
115: mixerctl -f $1 -n -w fea8-i7-master--
116: Consumer:Consumer_Control.Consumer:Mute 1
