Asus Prime Z790A WiFi USB A Ports not working after BIOS Update

I recently updated my Asus Prime Z790A motherboard BIOS to Version 1666 for the Vmin stability mitigation. However, after I updated my BIOS some of my USB A ports are not working anymore. Specifically it's the USB A ports at the back of the I/O panel. Has anyone else encountered this issue with this BIOS update? Has anyone figured out how to fix it?

Hello @FasterThanYou 

Thank you for reaching out to us.
Could you please confirm the previous BIOS version, the model of the devices that isn't working when connecting to the PRIME Z790-A WIFI rear USB type-A ports, the effected USB type-A ports you have tested, and whether you're using a hub or dock for the connection?

We recommend checking BIOS > USB Configuration to ensure the relevant ports are enabled and reviewing the Power mode and plan > Change advanced power settings to check for any power limits on the ports.
If needed, you can also roll back to the previous BIOS version 1663 to see if the ports function properly. 

Thank you.
