Just wanting to update for anyone else having this issue:
- I don't have an NZXT hub or any other device plugged into the additional internal USB header along the bottom of the board, and never have.
- I do have front panel USB plugged in for the case, which does seem to work so far.
- I have uninstalled and reinstalled every USB driver
- I have reached out to ASUS support
None of the actions above have resolved the USB problem. ASUS support gave a couple of suggestions from the above list, which I tried again to oblige the request, but their support system has absolutely no persistence so I had to open a new support request every single time my computer restarted, which was necessary for every single troubleshooting task they provided. This meant I had to open a new ticket and the roulette would spin to decide which support technician I got in contact with. They would not attempt to reach out to any prior support tech I had landed on, and would instead re-read the entire case history every time I provided my growing list of support ticket reference numbers.
The only suggestion Asus has provided at this point is to send my motherboard in for replacement - but obviously a several week turnaround in which I have to disassemble my entire computer and go computer-less for those weeks isn't something I'm interested in doing for the sake of getting half my usb ports to work. I'll just have to not get more USB devices and not be able to use most of the high speed ports that I paid for...
Currently on the most recent non-beta bios, still no change, and I don't expect that there will be any improvement to this issue once the current batch of beta branches shakes out, based on my experience so far.
