Output of bubblejail --version

0.9.1

Your distro name and version

Arch Linux

Description

Controller: 8bitdo pro 2 bluetooth

Simply enabling Joysticks and gamepads is not enough. For example if I have an emulator setup with bubblejail it can see my controller in xbox mode but not in switch mode. Everything works fine outside of bubble.

Hello @FeyrisTan

Do you have [joystick] service enabled? How does your /dev/input folder looks like then controller is plugged in? (ls -l)

The current gamepad detected algorithm is not perfect and will be reworked to use udev in the future. See #16 .

[joystick] is in the services file.

/dev/input has:
folders: by-id, by-path
event: 0-26 (0-28 with controller connected)
and then just js0 mice and mouse0-1

tried it with usb as well but same result. but it does work in "normal" xbox mode just not in switch mode.

Can you check the permission bits in the /dev/input. Currently the gamepad detection relies on the devices being other readable but maybe switch mode does not set that.

Also you can try running the strace to check if there is a some kind of path that is missing.

Looks like only js0 has the read permission. The current algorithm is very imperfect and relies on permissions of input device to have read permission. I have plans to use the udev but it has to wait for my library to add sd-device functionality.

Meanwhile you can try passing the missing eventX files using the debug service. This is very unreliable but see if that fixes the switch controller support.

Meaning like this?

[debug]
raw_bwrap_args = [
  "/dev/input/event27",
  "/dev/input/event28",
 ]

because that does not work

@igo95862

Like this:

[debug]
raw_bwrap_args = [
  "--dev-bind", "/dev/input/event27", "/dev/input/event27",
  "--dev-bind",  "/dev/input/event28", "/dev/input/event28",
 ]

See bwrap man page.

Do they have their own eventX device files?

I only see event27 and 28 being added when connecting the controller

Can you run udevadm monitor and post what it outputs when a controller gets plugged in?

monitor will print the received events for:

Hmmm... Maybe try adding the "--dev-bind", "/sys/devices/virtual/misc/uhid/0005:057E:2009.000C", "/sys/devices/virtual/misc/uhid/0005:057E:2009.000C",to the raw bwrap args? (not sure if it will work)
