irob:
The Cyclone Pro and the multilink should function nearly identically in this situation. The thread you referenced is indeed the culprit-- however, as that threat states, you should be able to communicate with the QG by cycling power on the device (while keeping the Cyclone Pro plugged in) after the initial attempt to communicate fails.
One of the main differences between the two interfaces, however, is that the Cyclone Pro has the ability to cycle the power for you if you've configured it to provide power to your target system.
So, technically this issue should be alleviated rather than exacerbated by the Cyclone...
