|
|
.Sh DESCRIPTION
|
|
.Nm
|
|
can be used to output or modify the state of a USB HID (Human Interface
|
|
Device).
|
|
If a list of items is present on the command line, then
|
|
.Nm
|
|
prints the current value of those items for the specified device.
|
|
If the
|
|
.Fl w
|
|
flag is specified
|
|
.Nm
|
|
attempts to set the specified items to the given values.
|
|
.Pp
|
|
The options are as follows:
|
|
.Bl -tag -width Ds
|
|
.It Fl a
|
|
Show all items and their current values.
|
|
This option fails if the device does not support the GET_REPORT command.
|
|
.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 l
|
|
Loop and dump the device data every time it changes.
|
|
Only 'input' items are displayed in this mode.
|
|
.It Fl n
|
|
Suppress printing of the item name when querying specific items.
|
|
Only output the current value.
|
|
.It Fl r
|
|
Dump the USB HID report descriptor.
|
|
.It Fl t Ar table
|
|
Specify a path name for the HID usage table file.
|
|
.It Fl v
|
|
Be verbose.
|
|
Repeating this option increases verbosity.
|
|
.It Fl w
|
|
Change item values.
|
|
Only 'output' and 'feature' kinds can be set with this
|
|
option.
|
|
.El
|
|
.Sh FILES
|
|
.Pa /usr/share/misc/usb_hid_usages
|
|
The default HID usage table.
|
|
.Sh SYNTAX
|
|
.Nm
|
|
parses the names of items specified on the command line against the human
|
|
interface items reported by the USB device.
|
|
Each human interface item is
|
|
mapped from its native form to a human readable name, using the HID usage
|
|
table file.
|
|
Command line items are compared with the generated item names,
|
|
and the USB HID device is operated on when a match is found.
|
|
.Pp
|
|
Each human interface item is named by the
|
|
.Qq page
|
|
it appears in, the
|
|
.Qq usage
|
|
within that page, and the list of
|
|
.Qq collections
|
|
containing the item.
|
|
Each collection in turn is also identified by page, and
|
|
the usage within that page.
|
|
.Pp
|
|
On the
|
|
.Nm
|
|
command line the page name is separated from the usage name with the character
|
|
.Sq Cm \&: .
|
|
The collections are separated by the character
|
|
.Sq Cm \&. .
|
|
.Pp
|
|
As an alternative notation in items on the command line, the native numeric
|
|
value for the page name or usage can be used instead of the full human
|
|
readable page name or usage name.
|
|
Numeric values can be specified in decimal,
|
|
octal or hexadecimal.
|
|
.Sh EXAMPLES
|
|
On a standard USB mouse the item
|
|
.Dl Generic_Desktop:Mouse.Generic_Desktop:Pointer.Button:Button_2
|
|
reflects the current status of button 2.
|
|
The
|
|
.Qq button 2
|
|
item is encapsulated within two collections, the
|
|
.Qq Mouse
|
|
collection in the
|
|
.Qq Generic Desktop
|
|
page, and the
|
|
.Qq Pointer
|
|
collection in the
|
|
.Qq Generic Desktop
|
|
page.
|
|
The item itself is the usage
|
|
.Qq Button_2
|
|
in the
|
|
.Qq Button
|
|
page.
|
|
.Pp
|
|
An item can generally be named by omitting one or more of the page names.
|
|
For example the
|
|
.Qq button 2
|
|
item would usually just be referred to on the command line as:
|
|
.Dl usbhidctl -f /dev/mouse Mouse.Pointer.Button_2
|
|
.Pp
|
|
Items can also be named by referring to parts of the item name with the
|
|
numeric representation of the native HID usage identifiers.
|
|
This is most
|
|
useful when items are missing from the HID usage table.
|
|
The page identifier for the
|
|
.Qq Generic Desktop
|
|
page is 1, and the usage identifier for the usage
|
|
.Qq Button_2
|
|
is 2, so the following can be used to refer to the
|
|
.Qq button 2
|
|
item:
|
|
.Dl usbhidctl -f /dev/mouse 1:Mouse.1:Pointer.Button:2
|
|
.Pp
|
|
Devices with human interface outputs can be manipulated with the
|
|
.Fl w
|
|
option.
|
|
For example, some USB mice have a Light Emitting Diode under software
|
|
control as usage 2 under page 0xffff, in the
|
|
.Qq Mouse
|
|
collection.
|
|
The following can be used to switch this LED off:
|
|
.Dl usbhidctl -f /dev/mouse -w Mouse.0xffff:2=0

.Sh BUGS
|
|
Some USB HID devices report multiple items with exactly the same usage
|
|
identifiers.
|
|
The current naming scheme does not provide the means to specify
|
|
which of a set of identically named items you are referring to.
