[Elecraft] K3s USB failure?

[Peter Dougherty]

Yes, the ports are the same, and this happened whether the PC was plugged in
to the laptop, or any USB port on the desktop. 

I've done a little bit more troubleshooting and it looks like a hardware
problem on the radio. When I plug the P3 interconnect into the P3 CAT stops
responding. With just the USB connection present it behaves. The instant I
plug in the P3 (the connector next to the USB plug on the K3s), I lose CAT
control. I'm leaving it unplugged at the moment, but it's not ideal.

That sounds like the virtual COM has been changed by the OS (Windows).

Have you checked the settings for CAT, PTT etc. in N1MM+ (Config > Configure
Ports...)

Is the Port for Radio the same like the one in the device manager?
