Check the pins on the RJ-45 connector on the K3S. They can be damaged if you accidentally insert something besides the RJ-45 plug. You may be able to straighten them, but if that object was metal and the K3S was powered on at the time there is probably going to be other damage.
I would remove the cable from the P3, then resigner it just to make sure. Also, to make sure - if the RJ-45 is _not_ plugged into the K3S, does the USB communications work properly? I think that is what you are indicating. If so, the connector and the cable are suspect. 73! Jack, W6FB > On Jun 23, 2019, at 4:34 PM, Peter Dougherty <li...@w2irt.net> wrote: > > Hmm.
