Post subject:  Unable to open communication link EV3 (SOLVED)

RobotC was previously running and the kernel had been downloaded etc. I uninstalled RobotC due to communication difficulties. I the reinstalled it. When attempting to download the kernel I get-
"Unable to open a communications link to the robot" with NO ERROR NUMBER.

Windows shows the device. Note even in the previous install I have never been able to download a program to the EV3.
In Mindstorms everything works perfectly.
Robot C 4.55 (9110) F/W 10.55
Solution
Evidently RobotC defaults need to be tweeked.
Robot>Lego Brick>Communications link setup
Needs to have Methods (lower left) set to USB and the "If usb connection.... block checked.
