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. Also if a USB device is
removed during runtime pin 6 of the LCD-connector will be asserted (and SmartCase DynamicUSB
Icon on LCD will be switched on) to indicate an SmartCase DynamicUSB event.
All USB-Ports (external and internal) beside USB Port 5 support SmartCase DynamicUSB.
The following device classes are specified within the USB specification.
