Which USB 2.0 doesn’t work? Do you mean USB 2.0 devices in any USB port (i.e 2.0 of 3.1) or in only the USB 2.0 ports
You have 8 Back Panel USB ports (2 - USB 2.0 by PS/2 port, 4 - USB 3.1 Gen 1 and 2 - USB 3.1 Gen 2 and internally 2 - USB 2.0 and 1 - USB 3.1 Gen1 headers.
What do you mean by “I am using the ports on the motherboard.” ? That seems odd as they are ALL on the motherboard. Do you perhaps mean the “on the Back Panel” or “the headers on the motherboard”. Also does the PS/2 keyboard not work when you are in the BIOS as you say “the USB keyboard does not work either.”?
Have you tried all the USB ports with the keyboard when in Windows 10 and in which ones is it recognised?
Which exact AMD CPU are you using?
Which BIOS version? There are 14 of them!
Be very careful because the sequence of updates
(''Note: before v2.00 Please install * Please install "AMD all in 1 with VGA driver ver:18.50.16.01_WHQL" or a later version before updating to this BIOS and so on.'' )
and the particular CPU model is very important i.e. Pinnacle, Raven or Summit Ridge.
Go into Device Manager by pressing the Windows Logo + X key combination on the keyboard and, from the list, click to select Device Manager.
Look for a yellow triangle containing an exclamation point over a device’s icon which indicates devices that aren’t working properly — possibly because of problems with their drivers.
Any ways that is a start.
Incidentally I have the same motherboard.
