Suspect Mayfly1.1

The cable I was using also went bad and I’ve marked it as suspect – its a distinctive pink cable.  I’ve inspected the Mayfly USB c on Mayfly1.1 with an Eye Loupe, and it is hard to inspect but nothing jumps out, seems OK.

I did have a USB current monitor in the testing before hand, and the current had gone up to 1.2A while charging a 2.2Ahr battery – but difficult to know if it was related. However the Mayfly options are not set to do a high charge, just 0.5A.

I switched to Linux Ubuntu to get more details, and a sturdy USB-C interface and I get with working White Cable into Mayfly1.0
