Consider the following scenario:

• You connect an IEEE 1394 standard-based camera to an IEEE 1394 standard-based external hub.
• You connect the IEEE 1394 standard-based external hub to an IEEE 1394 standard-based port on a computer that is running Windows Vista.

In this scenario, Device Manager in Windows Vista displays the camera device as expected. However, when you unplug the camera cable, the camera device does not unload successfully in Device Manager.

Note: If you unplug the cable from the external 1394 hub that is connected to the IEEE 1394 standard-based port, the camera driver unloads successfully.
