Visual Servoing Platform  version 3.2.0 under development (2018-12-11)
test1394TwoResetBus.cpp

Resets the IEEE1394 bus which first camera is attached to. Resetting the bus is "rude" to other devices because it causes them to re-enumerate on the bus and may cause a temporary disruption in their current activities. Thus, use it sparingly. Its primary use is if a program shuts down uncleanly and needs to free leftover ISO channels or bandwidth. A bus reset will free those things as a side effect.
