The USB Control menu determines how USB ports
and embedded devices operate at startup:
When USB Enabled is selected, all USB ports
and embedded devices are enabled.
When USB Disabled is selected, all USB ports
and embedded devices are disabled.
When Legacy USB Disabled is selected, all
USB ports are enabled under a USB-aware OS, but USB is not
supported during POST or RBSU. Legacy USB Disabled also disables
iLO 2 virtual devices.
When External USB Port Disabled is selected,
external USB ports are disabled. Under this option, embedded USB
devices still have full support under the ROM and OS.
