Have an Aorus b450 WiFi pro motherboard. When I plug a usb keyboard in and mash delete, the bios settings will not appear. I reset the CMOS and was able to enter on next boot due to the cmos being reset. I saved the settings, making sure fast boot was disabled and usb legacy and usb support was enabled. The problem persisted. When I get to a “no boot media, insert disk” message, I am fully able to use the keyboard. It seems the USB ports don’t activate until after the bios splash screen. Tried using different ports on the rear IO and case USB ports and none seem to work. Is there a specific one that is active?
