Our programmer thinks the problem is deeper than that. To show us, he held the power and USB cables and shook the samantha module around without it losing connection. He then put it on a robot and ran the robot the field wall, and it lost connection. He says it might be the hardware inside the samantha, not simply the cables. We may look for what's wrong - it'd be great for us teams know what the main problem is before worlds.
But still, it's working better than the bluetooth FCS.
