In some cases, USB ports on AMD 500 series motherboards may work incorrectly, which leads to incorrect operation of peripheral devices connected to them.
To solve this problem, download the new UEFI update from AMD:
- If you have an ASUS 500 series motherboard, go to the main support page of the company and select your motherboard model. There you can download the latest UEFI for your motherboard.
- If you have an MSI motherboard, you can download the update from the MSI website.
It is also expected that AGESA 18.104.22.168 will eventually fix this problem for previous generation motherboards with X470 and B450 chipsets.
