These errors indicate that your computer is completely unable to communicate with the USB device. It could be a problem with the device or a problem with the computer. Do you know that your devices work in a different computer? Have you found any devices that work in your computer? Can you get hold of a USB keyboard and see if it works with the BIOS during setup or pre-boot?
