# 8BitDo Ultimate 2 Controller

## Modes
Hold `B` (D-Input), `Y` (Switch) when turning the device on. Must be done after taking it out of the dock. `lsusb` will show the device ids.

- `6012`: DInput
- `6013`: Off with dongle
- `310b`: Xinput

**DInput**
- Hold `B` when turning the controller on.
- See [[#udev setup]], must be done before steam will see gyro etc.
- Support for Gyro, other buttons (without just binding those buttons to an existing button)
- Requires running the game through steam (steam provides a translation layer)
- *Note: if the firmware has mappings for say, the paddles, they will override what steam/dinput sees*.
- Note you can use steam to bind "extended buttons" and map gyro to some events (button down, etc), probably better to disable any gyro-when-x in the firmware. Select the game in steam, then press the controller button (NOT settings). You can do this within the game too,

**XInput**
- Broader support
- Hold `X` when turning the controller on.
- Must be in XInput mode to update the firmware!

## Turbo Mode
*Does not persist between turning the controller off.*

Hold `X|Y|A|B`, press `*`, now holding the button will auto-press, flashing the LED. Repeat to disable. You can do this for all face buttons at the same time.

Press `**` to enable "auto mode", where the button is pressed by default, holding stops the pressing.

## Rebinding
Rebind RL4 or Paddles by pressing `R4|L4` + `X|Y|A|B` + `square` to bind, button + square to unbind.
