8BitDo Ultimate Controller incorrectly recognized and calibrated

Hi!

I am trying out an 8BitDo Ultimate controler on my laptop using its wired connection.

I'm using a KDE desktop and in the "Game Controler" settings, I see that the device is recognized, but as an "8BitDo Pro 2 Wired Controller". The journal has the following messages:

Oct 06 15:41:45 kitpad kernel: usb 4-2: new full-speed USB device number 4 using xhci_hcd

Anyone know if I can get it to be recognized correctly?

Also, in the settings dialog, most of the buttons and axes work and show correct changes in values, except for the L2 axes/trigger. That has an initial value of 0 and changes to -1 upon press and remains stuck there. This is unlike the value for R2, which varies between [-32768, 32767] depending on the degree of press.

When I tried playing Xonotic, the view kept rotating, which I guess is due to the constantly pressed state of `L2`.

Is there any way I can fix that?

I've referred to this post in a KDE issue dealing with getting better support for input devices:
