Sudden Loss of K3S pc connectivity.

Today my pc no longer recognizes K3S
1.Radio RS232 port is set to usb/38400bd. Tried two different usb type b to type c cables. Tried plugging type c cable connection into both direct pc usb port and a hub usb connection. Neither connection worked. pc does not recognize radio 2 Device Manager recognizes Com 3 with no events. 3.Neither N1MM nor Logging program will connect over com 3/38400. I have been using this connection forever. Failure occurred today I wonder if this is KIO3 board failure? P3 works ok using RJ45 port on KIO3. I am stumped Jim K7EG |

Thanks Ray. Yes, but weeks ago. This issue happened today so doubt it is related to update

Any chance that it could have happened from a lightning strike? A friend of mine lost a couple of Serial Ports from a lightning strike...

Hi Jim, Do you still see the USB audio devices in the PC device list. Does a COMM port (dis)appear when (dis)conncting the USB cable. 73 Henk Verzonden vanaf mijn Galaxy -------- Oorspronkelijk bericht -------- Van: Jim Denneny <57JNDenneny@...> Datum: 04-11-2022 20:32 (GMT+01:00) Aan: Elecraft-K3@groups.io Onderwerp: [Elecraft-K3] Sudden Loss of K3S pc connectivity. 1.Radio RS232 port is set to usb/38400bd.

Thanks to all for the help. Even a tech at Elecraft was unable to unravel the issue. Could not connect to K3 Utility either. Device Manager told me Com3 was good. I was ready to ship radio to factory. I had RSA issued.
Last night, I performed routine, minor Win 10 update and suddenly Com 3 port is connecting to K3S again. K3 Utility also connects. Talk about a "snake in the grass". 73, Jim K7EG |

I just had the same problem, and it turned out to be a defective USB cable. There was a small amount of corrosion on one or more of the pins on the A side. Replacing the cable restored everything!
