Hi all I'm just going to post a few tips about getting your hardware to show up with link. As of June 2019 Windows 10 64-bit Version which is ver. 1809 OS Build 17763.529 and after that use 4.9.9.3 for Win x64 and you should be golden.
Remember, uninstall fully any iCue and Corsair Link software, restart once and re-install 4.9.9.3 Link and after if you wish to have iCue for RGB keyboard / headphones install that too. I use Link with Commander Mini which I recommend which, according to Corsair helps more items show up.
Currently I have all my fans and controls for fanspeed showing, my RGB colored LED belt and my power supply control panel. All of these items are Corsair brand.
Hope this helps! Please PM me if you have questions.
