Gamescope doesn't recognize the "system76 launch" keyboard as a virtual keyboard device

[MinmoTech]

This is probably an upstream issue (either with the keyboard or wlroots), but I thought it would be a good idea to report this here first.

If I try to start gamescope with gamescope -r 30 -- glxgears while only my System76 launch keyboard is plugged in I get the following error:

wlserver: [backend/headless/backend.c:82] Creating headless backend
vulkan: selecting physical device 'NVIDIA GeForce GTX 1080 Ti': queue family 2

fish: Job 1, 'gamescope -r 30 -- glxgears' terminated by signal SIGABRT (Abort)

I am on archlinux and my gamescope version is 3.11.43-1

If I have another "normal" keyboard plugged in, it sometimes works as expected.

This is my lsusb output:

It does list the keyboard correctly.

Relevant dmesg output:

Please do tell if I can provide more info or if I should report this upstream.
