Without other usb devices the keyboard works immediately. With them it takes 5 ish seconds for it to start responding. This is regardless of which device is discovered first (which I can manipulate), it seems to just wait for all of them. Is there a way to make it not do that?
I believe this is a hardware issue. Have you checked the USB options in the BIOS?
It works fine in bios and bootloader. This only happens during boot
