Sometimes the connection just drops and I found that when that happens, the telescope randomly slews sometimes. I just found the EQ direct cable to be much more reliable. I haven't seen one with a separate USB connection, just the hand controller serial connection. You can always try it to see if its performance is acceptable before spending more money on a new cable.
