Gamecube controller with Dobe adapter on Ubuntu not working properlly

[Galmo13]

Hi, I've been wanting to play some Gamecube games recently, so I've tried to setup my GC controller on Dolphin with the PC mode of my Dobe adapter, and it's only registering axis inputs (so both sticks and both analog triggers,), other inputs don't work. I've tried to switch to the Wii U/Switch mode of it, and the adapter is detected by Dolphin, but it doesn't register any input. I'm using Ubuntu by the way. Many thanks in advance
