USB Cords - Charge vs. Data

Hey guys,

I recently bought a used SkyCaddie (golf device that measures distances via GPS) and it didn't come with a USB cord. I tried using the USB that charges my PS3 controllers. The skycaddie charges but the software that it came with won't sync. I'm usually pretty good about solving these things.

Is it possible that the USB cord that I tried doesnt transmit data? Only charge?

Please help!

Thanks,
John
