After initially connecting a wired Xbox 360 controller or sending it
a command to change LEDs, a status/response packet is interpreted as
controller input. This causes the state of buttons represented in
byte 2 of the controller data packet to be incorrect until the next
valid input packet. Wireless Xbox 360 controllers are not affected.

Writing a new value to the LED device while holding the Start button
and running jstest is sufficient to reproduce this bug. An event will
come through with the Start button released.

Xboxdrv also won't attempt to read controller input from a packet
where byte 0 is non-zero. It also checks that byte 1 is 0x14, but
that value differs between wired and wireless controllers and this
code is shared by both. I think just checking byte 0 is enough to
eliminate unwanted packets.

The following are some examples of 3-byte status packets I saw:
01 03 02
02 03 00
03 03 03
08 03 00

This adds the VID/PID combination for the Xbox One version of the Mad
Catz FightStick TE 2.

The functionality that this provides is about on par with what the
Windows drivers for the stick manage to deliver.

What works:
- Digital stick
- 6 main buttons
- Xbox button
- The two buttons on the back
- The locking buttons (preventing accidental Xbox button press)

What doesn't work:
- Two of the main buttons (don't work on Windows either)
- The "Haptic" button setting does not have an effect (not sure if it
  works on Windows)

I added the MAP_TRIGGERS_TO_BUTTONS option but in my (limited) testing
there was no practical difference with or without. The FightStick does
not have triggers though so adding it makes sense.

This reverts commit 27b9d5a2.

I am reverting this one, while keeping the rest of the G920 support in,
so that it immediately starts working once proper HID-mode switching
is implemented.

Quoting Dmitry Torokhov for rationale:

==
It is wrong. Aside form the fact that IMO xpad.c is the wrong place for
this code to be in, why are we waiting for the input device to be
opened by userspace before we do the switch instead of doing it
immediately?

Several people (Simon Wood and Michal Maly) expressed the intent to work
on proper HID switching in a short term.

There's apparently a serial number woven into both input and output

Track the status of the irq_out URB to prevent submission iof new requests
while current one is active. Failure to do so results in the "URB submitted

Store pending brightness and FF effect in the driver structure and replace
it with the latest requests until the device is ready to process next
request. Alternate serving LED vs FF requests to make sure one does not
starve another. See [1] for discussion. Inspired by patch of Sarah Bessmer

Handle the "a new device is present" message properly by dynamically
creating the input device at this point in time. This means we now do not

This requires a workqueue as we are in interrupt context when we learn

Also properly disconnect any devices that we are told are removed.

When powering up a wireless xbox 360 controller, some wrong joystick
events are generated. It is annoying because, for example, it makes
unwanted moves in Steam big picture mode's menu.

When my controller is powering up, this packet is received by the
driver:
00000000: 00 0f 00 f0 00 cc ff cf 8b e0 86 6a 68 f0 00 20  ...........jh..
00000010: 13 e3 20 1d 30 03 40 01 50 01 ff ff              .. .0.@.P...

According to xboxdrv userspace driver source code, this packet is only
dumping a serial id and should not be interpreted as joystick events.
This issue can be easily seen with jstest:
$ jstest --event /dev/input/js0

This patch only adds a way to filter out this "serial" packet and as a
result it removes the spurous events.

as discussed here[0], x360w is the only pad that maps dpad_to_button.
This is bad for downstream developers as they have to differ between
x360 and x360w which is not intuitive.

This patch implements the suggested solution of exposing the dpad both
as axes and as buttons. This retains backward compatibility with software
already dealing with the difference while makes new software work as
expected across x360/ x360w pads.

This code was probably wrong ever since and is redundant with
xpad_send_led_command. Both try to send a similar command to the xbox360
controller. However xpad_send_led_command correctly uses the pad_nr instead
of bInterfaceNumber to select the led and re-uses the irq_out URB instead
of creating a new one.

Note that this change only affects the two supported wireless controllers.

The pad_nr corresponds to the lit up LED on the controller. Therefore there
should be no gaps when enumerating. Currently a LED is only re-assigned
after a controller is re-connected 4 times.

This patch uses ida to track connected pads - this way we can re-assign
freed up pad number immediately.

Consider the following case:
1. pad A is connected and gets pad_nr = 0
2. pad B is connected and gets pad_nr = 1
3. pad A is disconnected
4. pad A is connected again

using ida_simple_get() controller A now correctly gets pad_nr = 0 again.
