For some reason, Signal is no longer recognizing my Corsair K95 RGB Keyboard
UPDATE: I uninstalled SignalRGB and iCue. Reinstalled iCue and noticed some issues with keyboard functionality. I changed USB ports for the K95 then reinstalled SignalRGB. Voila. Maybe my keyboard is getting near EOL.
UPDATE: Sadly, now it can’t find my ASUS Motherboard fan controllers. Sigh. 
I have the same problem. I have run the suggested “unplug/esc/re-plug” scenario and that seems to fix it for a while, but it keeps coming back. Painful, because my PC is under my desk and I have to get down on the floor to unplug it, but then cannot reach the keyboard to hold the escape key. Takes 2 people to do it! Unfortunate they only recognize the device by it’s PC port #, so cannot plug into an extender.
