Thanks to all who replied to my Com Port problem! It is much easier to add info to the group en masse The following is happening in Device Mgr: when I turn the nanovna on or off, DM registers this hardware change I discovered 2 hidden ports Standard Ports 4 & 5 report: This device cannot start. (Code 10) The specified request is not a valid operation for the target device
Enhanced Ports 6 & 7 report:Currently, this hardware device is not connected to the computer. (Code 45) To fix this problem, reconnect this hardware device to the computer I have no clue how to "connect" these to the system [although, I tried updating the driver] When I turn-on the power supply, for my station, Ports 6 & 7 work properly. However, although Ports 3, 6 & 7 now appear in the drop list, in nano-app, when I click on either one, CONNECTed is displayed for a few seconds, then reverts to DISCONNECTed. Nano-saver still displays no ports and RESCAN does nothing. Can the order, in which I turn-on hardware & softwr, make a difference? Thanks to all, for previous, and upcoming, help. 73Phil, WF3W

You could try going into Device Manager->View->Show Hidden Devices then right-click and uninstall all of the USB devices. Then reboot and it should re-find all of the devices and assign them new ports. This may clear up a corrupted entry.

Short answer, yes, the order in which you turn on and off hardware and software can make a difference in how the ports enumerate.

NanoVNA-Saver uses the python serial package (pyserial) for serial port access. If you have python installed (I'm not sure if you install from the .exe, it actually installs python), you can see how pyserial sees your devices. At the command prompt(>), enter:

python -m serial.tools.list_ports -v

and you'll get a list of what it sees.

NanoVNA-Saver looks through that list looking for VID:PID combinations that it recognizes as being a NanoVNA.

Another thing to try is to remove the current device driver associated with that port, and then let Windows reinstall that driver when you plug in the nanoVNA...
