To quote from
http://technet2.microsoft.com/Window...mspx?mfr=true:

The system BIOS (for TPM and non-TPM computers) must support the USB mass
storage device class, including reading small files on a USB flash drive in
the pre-operating-system environment. For more information about USB, see
the USB Mass Storage Bulk-Only and the Mass Storage UFI Command
specifications on the USB Web site
(http://www.usb.org/developers/devclass_docs#approved/).

Probably not too helpful for you, but you might consider contacting Asus to
see if they have an approved BIOS. Also, have you tried different USB
drives? We've noticed in several cases that some drives, while behaving
normally after boot, fail in the pre-OS environment.
