That is the wierd part. One of the JRK units was in the drone, worked great a couple days ago, shows green but I cannot connect to it.
Yes, I did successfully connect one of the other JRK units to the computer and yes, I did test one of the bad ones with the same cable and on the same computer. Just to make sure, I did plug the good one back into the computer/cable combo and confirmed that it does work fine.
So, I have a known good cable, driver install, software install that does work with a JRK unit, but it doesn’t connect with either of the bad units - and yes, the status light on the JRK is green.
It is really odd… If I somehow blew up the controller, I would expect to smell burnt components or get a red status light. I would not expect green/no smell and no ability to talk to the unit. How frail are the usb components? Is it possible to damage the communication circuit without damaging the rest of the unit?
