Buried in the Macraigor web site's FAQ is the following important 
advice:

"What mode must my parallel port be in?

As far as the parallel port is concerned, a Wiggler is a simple uni-
directional device. It will work with the parallel port in any mode 
EXCEPT "ECP". It will NOT work in ECP mode at all.

Remember, the mode is set in the CMOS bios of your computer."

Boot your desktop PC and get it into "setup" mode. On my computer, 
you hit the DEL key just as it boots up to do this. Make sure that 
the parallel port is NOT in ECP mode (the default for modern PCs). I 
found that ECP mode gave me the "cable disconnected" message.

Good luck.
