Hi Ray,
Is it the case that (A) you sometimes get a good connection, but lose it when the cable is wiggled, or (B) you never get a good connection, but always get the “no module named serial” error?
If (A), you might consider trying a different USB cable if you have one handy, and please contact our store directly about getting a replacement cable or EBB if necessary. If (B), please say so. :)
