Issue

 

When a standard IEEE 1394 cable is attached to the system without a terminating device connected the IEEE 1394 Bus host controllers will disappear from device manager after 3 to 4 minutes.  The device reappears after the unit has been rebooted.

Resolution

 

Note that this is a typical issue with IEEE 1394 interfaces and not a malfunction of the computer.  To resolve this issue: remove the open cable or connect a terminating device.
