Add support for 8BitDo Ultimate (2.4Ghz proprietary protocol with receiver) controller #401

Closed adam900710 closed 1 year ago

adam900710 commented 1 year ago

Version of xpadneo

0.9.5

Controller Model

8BitDo Ultimate 2.4Ghz Controller with Charging Dock https://www.8bitdo.com/ultimate-2.4g-wireless-controller/

Please don't get confused with the bluetooth version, this one only supports its proprietary 2.4Ghz protocol.

Connection mode

Describe your feature reqeust

In fact, there is already working method using xboxdrv: https://aur.archlinux.org/packages/8bitdo-ultimate-controller-udev

Describe the solution you'd like

Like to see xpadneo just adds the extra device id and needed quirks for that gamepad.

Describe alternatives you've considered https://aur.archlinux.org/packages/8bitdo-ultimate-controller-udev Which uses xboxdrv to handle the device.

Extra info

The receiver and the gamepad USB connection have the same USB id(s):

2dc8:3106: 8BitDo 8BitDo Ultimate wireless Controller for PC
2dc8:3109: 8BitDo IDLE

The hid id is 0003:2DC8:3109, from the hid-generic output (only on IDLE):

[  105.822181] hid-generic 0003:2DC8:3109.0008: hiddev98,hidraw5: USB HID v1.10 Device [8BitDo IDLE] on usb-0000:00:14.0-1/input0

Tried modifying the modprobe.d rules, but not working:

# For 8bitdo Ultimate 2.4G recevier/gamepad
alias hid:b0003g*v00002DC8p00003106 hid_xpadneo
alias hid:b0003g*v00002DC8p00003109 hid_xpadneo

xpadneo does not currently support USB devices. This is technically a USB device due to the receiver, xpadneo currently only talks to Bluetooth devices (or rather: HID devices). If you connect the controller in Bluetooth mode, it should already be supported.

But still, it is a HID device. So it may be possible to unbind the device from hid-generic, then rebind to hid-xpadneo via sysfs. But unless it's using an Xbox-compatible HID protocol, xpadneo won't support it. hid-generic should already support the controller by default.

What's the real problem with using hid-generic? Are any functions missing?

That said, if your controller is Switch-compatible, future updates to xpadneo may support it.

I guess since xboxdrv can handle it, the hid protocol should be mostly XBOX compatible?

The hid-generic problem is, no joystick interface at all, thus most programs can not support the device.

Anyway, thanks for the detailed explanation, I totally understand it's not going to be supported anytime soon, thus I'm fine using the xboxdrv solution for now.
