DESCRIPTION
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.

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

specified, current values will be requested from device.
SYNTAX
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
character `.'.
Some devices give the same name to more than one item. usbhidctl
supports isolating each item by appending a `#'. character and a decimal
item instance number, starting at zero.
