One of the front USB ports of my Asrock B450M Pro4 mainboard is not working at all. The other one is working fine. BIOS is 3.60 which is running fine under Windows 10 Pro. There is no issue shown in Windows device manager. I also tried to remove the Windows driver manually and reboot the system. It ends in the same result. Everything is working except that one front USB. I also checked the mainboard connector. The strange thing is that I installed Windows from USB stick using that no longer working port. After that I upgraded BIOS from 3.30 to 3.60.
Are there any ideas what to do? ]]> Sun, 29 Sep 2019 15:19:50 +0000 https://forum.asrock.com/forum_posts.asp?TID=12548&PID=68424&title=only-one-of-two-front-usb-ports-working#68424
