I created an account on this forum just so I could reply to Syberon's comment from 2 years ago to say THANK YOU. I spent several hours trying to figure out why my iCUE Application interface was showing "unavailable".
For future readers, the 3 settings on the bottom of your Dark Core RGB Pro gives the following results:
When plugged in, iCUE connected and displays: USB MODE
When Bluetooth on, iCUE is NOT connected and displays: UNAVAILABLE
When Wifi on (2.4gh and uses dongle), iCUE is connected and displays: WIRELESS MODE
I don't know why I didn't try the 3rd option but I'm glad I discovered an answer before drafting a huge follow-up with Corsair support. Hopefully this post will also help with SEO so others can find this help quicker than I did :laughing:
