.El
|
|
.Sh SYNTAX
|
|
.Nm
|
|
compares 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
|
|
Some devices give the same name to more than one item.
|
|
.Nm
|
|
supports isolating each item by appending a
|
|
.Sq Cm \&# .
|
|
character and a decimal item instance number, starting at zero.
|
|
.Sh FILES
|
|
.Bl -tag -width 30n
|
|
.It Pa /usr/share/misc/usb_hid_usages
|
|
The default HID usage table.
