Restrict USB Devices
Specify the following categories of USB devices to enable:
● Allow all USB devices
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
Windows 7 and other non-Windows configurations. Default is 'All UEFI' for Windows 8.1 or later.
