[chirp_users] VX-6R won't download from radio

I'm a newby to the group ... not having any problems using the software with my Baofeng UV-B5, but I can not download my Yaesu VX-6R to the software. Once I press the band button to begin the download , a few seconds go by LCD reads out ERROR. I don't see any obvious VX-6R problems listed ... but can anybody confirm that the current build is working fine with the VX-6R? Or do I have a cable problem? Using Windows 7 and the driver is working fine for the other radio. So I either have a Vx-6R cable problem ... likely is a counterfeit Prolific chip in it ... OR WHAT ELSE? Any thoughts?

Warm regards, Barth n2abc
