B550m PRO4 usb device disconnecting and reconnecti

quantummoon wrote: Well, like everyone said it was the USB-C port. I plugged my WiFi usb receiverwith a USB-A to USB-C adapter into the USB-C port and everything is fine. The driver for that port (port 5) is now correctly installed. What a huge waste of time after installing new bios, chipset, etc. Hope they fix this and this helps someone else

I can also confirm unplugging the adapter from the USB-C part is fine. The driver is still installed correctly. I imagine windows needs to install a driver for the USB-c port while something is plugged in. Will update if anything changes.

Just updated the BIOS and it?™s still happening. Some device keeps reconnecting

Hi I was experiencing same problem but it's gone for now I had horrible boot times and laggy bios out of blue it stopped.

I think today beta bioses were released did someone tried it out ?

Replace the £ by a question mark in the above URL, I don't know what's up with this forum.

I wanted to get in touch again on this topic. I was in contact with ASRock's support and they recommended that I send the board back to the supplier. I did that and have now received a new board. So far the BIOS has been running smoothly and Windows 10 has remained quiet. There is now version 3.00 on the board, I will not make a new BIOS update on it as long as it works. I was told it could be due to the AGESA drivers, but I can't guarantee that.
