Anyone have any advice on getting my new Yaesu VX-8DR to communicate? 

Each time I try the radio will show "ERROR" after a few moments and a short time later CHIRP will show "An error has occurred Failed to communicate with the radio: No response from radio"

I've tried the following:

-2 different cables (one Prolific from GoodQBuy and one FTDI from Valley Enterprises) both produce same result.

-Setting radio into clone mode and starting to transmit only after starting receive in CHIRP.

-Downloaded newest version of CHIRP.

-Ran updates and rebooted PC.

-Switched USB ports (with cables).

-Updated drivers for both cables.

-Factory reset on radio.

-Selected other radio models when downloaded (VX-8, VX-8R and VX-8GE).

-Checked connection at the radio and it appears to be tight. 

I've used CHIRP on Baofeng, BTECH and a few other brands/models and never encountered an issue that wasn't easily resolved. 

Any help or advice is much appreciated!
