If your computer tries to enter suspend mode and the request is rejected, the device in the USB connector might be disabled. If this occurs, do a hot-unplug-and-plug operation for the USB device.
If the setting of the USB connector on your computer is enabled (the default setting), do not use a PCI Video Card and a PCI Network Card at the same time in the SelectaDock III docking station. If both cards are inserted, your system cannot boot.
Do not disable the USB connector on the SelectaDock III. If you disable it, the system might hang during a hot- or warm-dock or -undock operation. If this occurs, restart the system.
