I've had a Commander Core XT working for almost a year now without any problems. Several regular PWM fans, 3 Corsair QL-series RGB fans, 2 temp probes, and a series of RGB strips on the 3 pin RGB header.
I updated the firmware today after getting a notification, and the update seemed to go without any problems. Afterwards though my RGBs are all blinking white. Just a slow once per second blink. I'm not able to control any of the RGB devices with iCue.
I've rebooted several times, moved the CORE XT to a different USB header, disconnected all but one RGB device, and reinstalled the firmware and iCUE with no effect. All the temp monitoring and fan control work just fine.
Running auto-detect also no longer detects any RGB devices, it just sits at the auto-detection screen forever, regardless if all, 1 or no fans are plugged in.
I've looked for an old firmware file to try down-grading, but I can't seem to find any.
Any ideas, or is this just an RMA.
