Notes
There are some "class" specific data that are exchanged between the PS3 and DS3 when it connects, via control transfer. I suspect some of these are calibration or configuration values. Some of it probably have Bluetooth pairing info inside, which I might need to sniff Bluetooth traffic to see, because I can't obtain the PS3's MAC address easily yet.

HID Report Mapping
Byte 0 is the report ID
Byte 1 is reserved
Byte 2, 3, 4, and 5 contain button info. Active high (1 means pressed, 0 means released). See table:
| bit | 7 | 6 | 5 | 4 | 3 | 2 | 1 | 0 |
| byte 2 | D Left | D Down | D Right | D Up | Start | R3 | L3 | Select |
| byte 3 | Square | X | Circle | Triangle | R1 | L1 | R2 | L2 |
| byte 4 | ? | ? | ? | ? | ? | ? | ? | PS |
| byte 5 | ? | ? | ? | ? | ? | ? | ? | ? |
Byte 6 is left stick X axis; byte 7 is left stick Y axis; byte 8 is right stick X axis; byte 9 is right stick Y axis; top left is 0
Byte 13 to byte 24 contains analog button data, 8 bits each, 0 is released and FF is fully pressed. The ordering follows the order of the bits shown in the table above.
Byte 40 and 41: accelerometer X axis, little endian 10 bit unsigned
Byte 42 and 43: accelerometer Y axis, little endian 10 bit unsigned
Byte 44 and 45: accelerometer Z axis, little endian 10 bit unsigned
Byte 46 and 47: gyroscope, little endian 10 bit unsigned
Bluetooth
There appears to be a ALPS module on the circuit. Unable to obtain any good datasheets or manuals at this time.
