Root 3 CNC - USB Booster

In order to move my laptop a safe distance away from sawdust clouds I purchased a long USB cable:

JSAUX Printer Cable, 15 feet

 Unfortunately attempting to use the cable resulted in the following error:


15 feet is at the end of the USB specification, and apparently was just too far for the signals to travel (either voltage drop or latency, not sure what was the problem here).  To remedy the problem, I found a USB booster and small 1 foot A-B converter cable:

Printer Cable 1 Foot, A Male to B Male


IOGEAR USB 2.0 Booster Extension Cable, 16 Feet


Using these two cables allowed the Arduino/RAMPS board to connect to the laptop at a 15 foot distance without issues.
