Hi there, I got the same problem since I have the riing quads. I had the same problems with my old Gigabyte motherboard. That was the Z390. Now I have the ASUS Z790 Hero. Same crap.
Then sporadically when restarting one controller is not recognized or the other controller is not recognized. If I then uninstall the USB device in the device manager and restart it, it usually works. But not now. I tried different variants on the mainboard. Always the same failures. I even tested a USB 3 to USB 2 adapter. Always the same problem. The controllers fail at least once every 5 times. What can we do?
After I restarted just 5 times and uninstalled the USB drivers several times, it still didn't work. Now I have swapped the two USB ports on the mainboard. Now it's working again. The only question is for how long.
