I have this weird issue, evolved from a problem I had from the past with the same keyboard and it seemed to be fixed in recent updates. But now, if Steam app is on and I press LEFT SHIFT the keyboard will disconnect and I’ll have to unplug and plug it again. If (some) wine games are running it’ll trigger also.
I’ve tried different kernels (5.4-5.8-5.9) and disabling USB autosuspend through TLP and powertop.
Keyboard is a Cooler Master MK850, and it works flawlessly on the same system on other OS partitions (Ubuntu and Win).
I want to add I just tested logging out of steam beta, and the problem is gone there (persists in some wine games-apps). I f roll in beta again the problem is back. My fear is when the beta is live to get this problem persistent.

Hello there, this problem persists, I’m doing some digging and I think it has to do with the fact that the keyboard has Aimpad technology, meaning is recognized as a xbox controller by steam and the system.
Why it disconnects as soon as I press Left Shift (and only that key) is a mystery to me, in these months I’d been trying other distros, kernels, configurations, etc … But the problem is still there.
Well, more testing, it’s almost there, but I can’t figure it out since my linux-fu is nonexistent.
I did a full new Manjaro reinstall, still using KDE, everything working right finally. No more keyboard shutting down when pressing left shift.
Well, no more until I tried a new game with controller support. I had to click on game properties on steam, properties>controller> and change default settings to “disable steam input”. Xbox controller worked in game, all good, but when I launched another game and pressed left shift, NOOO, it happened again. Now, no matter after deleting steam folder and reinstalling games, reboot, and such, still same problem.
Before that I won’t have this 3 controllers listed on steam,
Something was triggered as system level configuration, I think in my ignorance possibly related to udev rules or something like that, and now the keyboard is also detected as 3 controllers as before I reinstalled Manjaro.
I have the idea that the solution could be blacklisting this 3 connections of my keyboard to even be available to be detected, but honestly I don’t know if that’s the solution or even how to pull that out on the terminal.
