Turns out one of the USB ports on the ROG FPS-II card is not working. Will have to contact Asus for a new one. Right now, I have to forgo connecting my power supply to the USB and monitoring it in iCue. I have a Z790-i motherboard. There are no actual USB headers on the motherboard. You have to attach the ROG FPS-II card to the motherboard to get USB headers. I guess that just comes with the turf of having a Mini-ITX motherboard. At least I can just get a new ROG FPS-II card and install it, rather than having to send back the whole motherboard.
