I plug in my NanoVNA V2Plus4.
Looking at the device manager ....
Windows 11 gives me the little happy "I'm connected" Blip sound
No new COM ports were created.
Under the Universal Serial Bus Controllers heading a new USB to UART Adapter shows up.
OK, so how do I get the nanoVNA software to connect?

Hi, this means Windows doesn't have the correct driver associated with the
device. Some older Windows versions require the Cypress driver (
https://nanorfe.com/nanovna-v2-software.html#nanovna-qt), did you try
installing that? If you've installed it already, you may also try
uninstalling it as some users have indicated that the driver is not needed
on newer Windows versions.
Thanks,
NanoRFE Support

This is Windows 11.
I tried it with and without that driver, restarting the computer between
attempts.

FIXED!!!😁😁😁😁😁😁
What was the problem and how did it get fixed???
This **was** a Windows 10 machine which got ported to a Windows 11.
As a Windows 10 machine, it had the official Cypress driver installed and
everything worked just fine.
When it was ported to Windows 11, the driver (which doesn't work under
Windows 11) was ported with it.
A friend of mine heard of my issues and removed every vestige of the driver
and all its tendrils from the computer and now it works flawlessly.
I am a happy camper. 😃

Ralph,



I’m having the exact issue you encountered. Perhaps your friend could elaborate a bit on what they did to expunge the Cypress driver? I’m guessing it involved the registry and some spelunking into system32?



Love your YouTube content!
