I had a 1b1c:1b38 Corsair Corsair Gaming K70 RGB RAPIDFIRE Keyboard that worked fine with ckb-next immediately after installing it on Fedora, but it’s been over a year since I last tried.
I only used OpenRGB on Windows but it worked fine and detected.
A quick search on ckb-next’s GitHub didn’t show any results for 1b1c:1bff, so I’m not too sure if it’d support that keyboard out-the-box. Depending on how different it is, maybe support could be made easily from an existing device on ckb-next’s end.
iCUE through Wine I wouldn’t expect to work, but it’ll likely need to access the keyboard through USB (possible hid/raw with Wine permissions allowed). Depending on how new that keyboard is, I’d recommend either V2 CUE or the last V3 version (iCUE 4+ are bloated).
If the keyboard saves lighting states to its own hardware, it’d probably be easiest to do it from a different computer with Windows real quick (I preferred iCUE on a different Windows PC for my HARPOON mouse Hz/DPI config vs ckb-next on Linux).
