Yea, the C6 stuff is a bit silly at times.

I was having issues with it the other day. Just wouldn’t send the data although it kept saying it had.

I fought and fought with it.

In the end what seemed to fix it was to alter the configuration, save it, then set the configuration back to what it was before and save again - all of the sudden it worked.

Maybe that’s how you got yours to work.

P.s. if it were a loose cable the computer would most likely not recognize that there is a device and C6 would of complained when you opened it.
