[[ Protocol Descriptions ]]
===========================
General:
========
The following was learned through a combination of guessing and
looking at the Windows, MacOSX and Linux Kernel drivers. No gurantee
for correctness.
Use usb_interrupt_read() not usb_bulk_read(), the later one fails with
the Xbox360 guitar.
Xbox:
=====
The A, B, X, Y, black and white buttons on the Xbox pad are 8bit pressure sensitive.
Led: doesn't have LEDs
+----------- small weight (right side), 0-255
v v-- large weight (left side), 0-255
Rumble: { 0x00, 0x06, 0x00, s, 0x00, large };
^-- length of the message

Xbox360 Controller
==================
The Xbox360 controller doesn't have pressure sensitive A,B,X,Y,LB,RB
buttons like the Xbox controller, only LT and RT are analog.
On first connect the controller sends:
len: 3 data: 0x01 0x03 0x0e // current LED status
len: 3 data: 0x02 0x03 0x00
len: 3 data: 0x03 0x03 0x03 // Rumble Status (0x00 in the last pos means rumble is disabled, 0x03 is default)
len: 3 data: 0x08 0x03 0x00
len: 20 data: 0x00 0x14 0x00 0x00 0x00 0x00 0x69 0xed 0x23 0xff 0x6b 0x00 0x15 0x03 0x00 0x00 0x00 0x00 0x00 0x00
len: 20 data: 0x00 0x14 0x00 0x00 0x00 0x00 0xfc 0xec 0x23 0xff 0x6b 0x00 0x15 0x03 0x00 0x00 0x00 0x00 0x00 0x00
The first four lines are unknown, but seem to be always the same, the
"len: 20" ones are event data of the following form. The controller
sends them two times on each button press and also two times on first
connect.
Commands send to the controller:
--------------------------------
,--------- type of message
v v-- length of message
LED: { 0x01, 0x03, LED_STATUS };
LED Status Update Message, send out after one has changed the led status:
{ 0x01 0x03 LED_STATUS } (blinking states are reported as non-blinking)
+-------- large weight (left side), 0-255
v v-- small weight (right side), 0-255
Rumble: { 0x00, 0x08, 0x00, large, small, 0x00, 0x00, 0x00 };
^ ^-- length of the message
`--------- type of message
Unknown:
sending { 0x02, 0x03, INT } causes a reply of { 0x03, 0x03, INT } (values of 0-3 are supported)
sending { 0x02, 0x03, 0x00 } causes future rumble update messages to be ignored, this seems to be permanent, even disconnecting the controller doesn't reset it

Xbox360 Guitar
==============
The Xbox360 Guitar behaves the same as a regular Xbox360 controller
and talks the same protocol just with the meaning of a few buttons and
axis changed. The guitar doesn't have rumble support.

Xbox360 Wireless
================
The wireless reciever acts as a single USB device, each of the four
controller is on a seperate Interface together with the headset port:
Interface 0:
Endpoint 1: Controller 1
Endpoint 2: Headset 1
Interface 1:
Endpoint 3: Controller 1
Endpoint 4: Headset 1
Interface 2:
Endpoint 5: Controller 1
Endpoint 6: Headset 1
Interface 3:
Endpoint 7: Controller 4
Endpoint 8: Headset 1
