Yeah, I tried it with hyprland and COSMIC. I’m currently using KDE, but if I get enough energy to configure hyprland on NixOS, I’ll switch to that. COSMIC wouldn’t let me use Steam, so I had to switch back to KDE. Tiling on COSMIC was really nice, though.
I’ve had old Ugreen devices with a similar setup. Notably a KVM that fried my keyboard bc they failed to follow USB spec.
A-to-A cables are, in general, a hardware design smell. It’s best to avoid devices that don’t care enough to follow the spec.
