SmartCase DynamicUSB
This is hardware security circuit which will disable the USB-port if a USB-device is removed so no
other USB-devices can be attached. Goal is that no data can be stolen by connecting i.e. a USB-
stick. This function is completely realiszed in hardware and BIOS and therefore totally independent of
any OS or Software interaction.
This feature needs to be enabled via BIOS-Setup. During boot phase BIOS will allow specified
attached USB-devices (not allowed devices will not work). Ports where no device is connected will be
disabled by BIOS automatically. If a USB device is removed system must be power-cycled (S4 or
S5-state) before any other USB device can be detected on this port again. In addition, following
removal of a USB device during the runtime, the USB light begins to flash in order to indicate a
SmartCase DynamicUSB event.
All external USB 2.0 ports (I/O area and front) offer support for SmartCase DynamicUSB. The
USB 3.0 ports are deactivated with SmartCase DynamicUSB.
The following device classes are specified within the USB specification. Bold/cursive written classes
are not allowed USB devices (if SmartCase DynamicUSB is enabled) – ports with such devices
connected during BIOS post phase will be disabled by BIOS.
