     usbhidctl -- manipulate USB HID devices

     usbhidctl -f device [-t table] [-v] [-x] -r
     usbhidctl -f device [-t table] [-l] [-v] [-x] [-z]	-a
     usbhidctl -f device [-t table] [-l] [-n] [-v] [-x]	[-z] item ...
     usbhidctl -f device [-t table] [-v] [-z] -w item=value ...

     The usbhidctl utility can be used to dump and modify the state of a USB
     HID (Human	Interface Device).  Each named item is printed.	 If the	-w
     flag is specified usbhidctl attempts to set the specified items to	the
     given values.

     The options are as	follows:

     -a	     Show all items and	their current values if	device returns.

     -f	device
	     Specify a path name for the device	to operate on.

     -l	     Loop and dump the device data every time it changes.

     -n	     Suppress printing of the item name.

     -r	     Dump the report descriptor.

     -t	table
	     Specify a path name for the HID usage table file.

     -v	     Be	verbose.

     -w	     Change item values.  Only 'output'	and 'feature' kinds can	be set
	     with this option.

     -x	     Dump data in hexadecimal as well as decimal.

     -z	     Reset reports to zero before processing other arguments.  If not
	     specified,	current	values will be requested from device.

     usbhidctl 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.

     Each human	interface item is named	by the "page" it appears in, the
     "usage" within that page, and the list of "collections" containing	the
     item.  Each collection in turn is also identified by page,	and the	usage
     within that page.

     On	the usbhidctl command line the page name is separated from the usage
     name with the character `:'.  The collections are separated by the	char-
     acter `.'.

     Some devices give the same	name to	more than one item.  usbhidctl sup-
     ports isolating each item by appending a `#'.  character and a decimal
     item instance number, starting at zero.

     /usr/share/misc/usb_hid_usages The	default	HID usage table.

     usbhid(3),	uhid(4), usb(4)

     The usbhidctl command appeared in NetBSD 1.4.
