[connector]---------length---------////////coil length/////////-------length-------[connector]
example: [mini-b]-------2"--------////////8"/////////-------4ft-------[USB A]
The example above would have the coil start 2 inches from the mini-B connector and be 8 inches long. After the coil ends there would be a 4ft straight portion to the cable making the effective length 4ft10in.
NOTE: The maximum coil length is 13 inches
