Hello everyone, I apologize for my engine English.

My problem: after updating bios v.3.43 (x470 taichi), USB 2.0 Header (USB_1_2) & USB 2.0 Header (USB_3_4) stopped working. I'm sure that in BIOS v.2.0 these ports worked fine. All other usb header work. I did not find the settings associated with USB 2.0 in the BIOS. Starting from version 1.10, all releases were installed (now I can?�t lower it .... also to 2.00 from windows).

Request to the owners of the specified motherboard to check these ports? I want to believe that this is a software bug, and not a failed controller ...
