Input: xpad - update docs to reflect current state

The last time this documentation was accurate was
just over 8 years ago. In this time we've added
support for two new generations of Xbox console
controllers and dozens of third-party controllers.

This patch unifies terminology and makes it explicit
which model of controller a sentence refers to.

It also expands certain sections to address the latest
versions of Xbox controllers.

Thus this documentation should now be useful to
end users and not contain out-right untruths.

This is the patch's second revision. Prior versions
of this patch altered the driver's TODO list. That
change has been pulled out of this documentation
update patch.

xpad - Linux USB driver for X-Box gamepads
xpad - Linux USB driver for Xbox compatible controllers
This is the very first release of a driver for X-Box gamepads.
Basically, this was hacked away in just a few hours, so don't expect
miracles.
This driver exposes all first-party and third-party Xbox compatible
controllers. It has a long history and has enjoyed considerable usage
as Window's xinput library caused most PC games to focus on Xbox
controller compatibility.
In particular, there is currently NO support for the rumble pack.
You won't find many ff-aware linux applications anyway.
Due to backwards compatibility all buttons are reported as digital.
This only effects Original Xbox controllers. All later controller models
have only digital face buttons.
Rumble is supported on some models of Xbox 360 controllers but not of
Original Xbox controllers nor on Xbox One controllers. As of writing
the Xbox One's rumble protocol has not been reverse engineered but in
the future could be supported.

Driver updated for kernel 2.6.17.11. (Based on a patch for 2.6.11.4.)

- if you are using a known controller
- if you are using a known dance pad

If you set dpad_to_buttons to 0 and you are using an unknown device (one
not listed below), the driver will map the directional pad to axes (X/Y),
if you said N it will map the d-pad to buttons, which is needed for dance
style games to function correctly. The default is Y.

dpad_to_buttons has no effect for known pads. A erroneous commit message
claimed dpad_to_buttons could be used to force behavior on known devices.
This is not true. Both dpad_to_buttons and triggers_to_buttons only affect
unknown controllers.

All generations of Xbox controllers speak USB over the wire.

- Wireless Xbox 360 controllers require a 'Xbox 360 Wireless Gaming Receiver

- Wired Xbox 360 controllers use standard USB connectors.
- Xbox One controllers can be wireless but speak Wi-Fi Direct and are not
yet supported.
- Xbox One controllers can be wired and use standard Micro-USB connectors.
Before you can actually use the driver, you need to get yourself an
adapter cable to connect the X-Box controller to your Linux-Box. You
can buy these online fairly cheap, or build your own.
1.1 Original Xbox USB adapters

Using this driver with an Original Xbox controller requires an
adapter cable to break out the proprietary connector's pins to USB.
You can buy these online fairly cheap, or build your own.
Such a cable is pretty easy to build. The Controller itself is a USB
compound device (a hub with three ports for two expansion slots and
the controller device) with the only difference in a nonstandard connector
(5 pins vs. 4 on standard USB connector).

Once you have the adapter cable and the controller is connected, you need
to load your USB subsystem and should cat /proc/bus/usb/devices.

Once you have the adapter cable, if needed, and the controller connected
the xpad module should be auto loaded. To confirm you can cat

Currently (as of version 0.0.6), the following devices are included:
original Microsoft XBOX controller (US), vendor=0x045e, product=0x0202
smaller Microsoft XBOX controller (US), vendor=0x045e, product=0x0289

IDs see the xpad_device[] array[6].
As of the historic version 0.0.6 (2006-10-10) the following devices
were supported:

The driver should work with xbox pads not listed above as well, however
you will need to do something extra for dance pads to work.
Unrecognized models of Xbox controllers should function as Generic
Xbox controllers. Unrecognized Dance Pad controllers require setting
the module option 'dpad_to_buttons'.
If you have a controller not listed above, see 0.3 - Unknown Controllers
If you have an unrecognized controller please see 0.3 - Unknown Controllers
