● Allow only keyboard and mouse
Allow all but storage devices and hubs.

When some devices are restricted, the system will disable USB ports that do not meet the allowed
criteria. This feature is usually combined with similar policies within the operating system since USB devices
can be moved to different ports. The ports disabled by the BIOS will remain disabled until the system is
restarted.
These policies control whether Legacy Option ROMs or UEFI drivers are loaded. Default is 'All legacy' for non-
Windows configurations. Default is 'All UEFI' for Windows 10.
