My Steelseries Prime Wireless only has basic functionality working. I could run the software via Wine or VM (don’t remember) but it didn’t remember the settings after a power cycle of the mouse or the PC (also don’t remember).

why doesnt GNOME have a maximize button

Probably because you can double-click the window ‘bar’ to achieve the same.

Great job! Is there a way to donate to the project?

I looked it up and it seems to be the 2020 version. I recently got it with a Steam Deck that I bought second hand.

My Xbox Wireless Controller couldn’t connect with Bluetooth until after a firmware update. The update required a Windows machine and the Xbox Accessories app (VM didn’t work) or an Xbox One (360 didn’t work).
