Andrew, I swapped the board out for the second one. It too has been solid. Not a single glitch and I am using the hub and extension cable as well. The BB60C has been in use a fair amount. It seems the Dell’s USB ports may just not be as clean. I guess you could buy the same PC and see if you could replicate the problem. Maybe there would be a way to allow the BB60C to auto recover. Attached my latest video with Labview. Things are a little cleaner and I have a much better understanding how to use the API now.
