New setup, USB 2.0 not working.

crwdns2934249:0crwdne2934249:0:

Hello everyone,

I have built a new PC, but USB 2.0 does not work. When I connect a keyboard I don't get into the BIOS or something like that. When I connect a PS2 keyboard, I do enter the bios. Once in the BIOS through the PS2 keyboard, the USB keyboard does not work either. When I use a USB stick 2.0, it is not recognized in the BIOS. A USB stick 3.0 is seen. I am using the ports on the motherboard. It concerns the ASRock B450 Pro4. All USB ports provide 5V.

Who can help me with this problem?

Thanks in advance!
