Hello all,

I have a NanoVNA-H wich used to work under W10 with Nanosaver app. After upgrade to W11, when I connect the NanoVNA to usb port nothing happens, no new com port is seen under device manager.
Wonder if anyone had the same problem. Any help its welcome.
thank you.

If you can't see the NanoVNA-H as a COM port in Windows 11 after plugging it in that means that the driver is not installed. Windows 11 should install it automatically but sometimes it fails to load. It could be sitting in your "Optional Updates" and you need to select it for installation. Use the search box to find "Windows Update" and select it. Then go to "Advanced Settings" and select "Optional Updates" (see screenshot below). You may find the driver is there waiting to be installed.

Some drivers will not install in Windows 11 because "Memory Integrity" is on and the driver does not meet Microsoft safety standards. If you turn off Memory Integrity the driver can then be installed.

Dear Roger,

thank you very much for reply. In the meanwhile problem solved, it was the usb cable which was interrupted inspite of looking like brand new.
That is why I thought that might be a W11 driver problem. Thank you again, wish you all the best.
