Re: Windows 7 USB Driver problem - not working


 

Checking the Windows device driver properties shows nanovna to be using ChibOS/RT Virtual Com port and Windows recognizes device being attached / removed.
You could replace that driver with this:


Virtual COM port operation to nanoVNA can be confirmed using .e.g putty.exe


I don't bother with a .msi installer; the standalone .exe works fine.

Try sending `help` from putty:
/g/nanovna-users/wiki/shellcommands

Nanovna-Saver uses pyqt5, which can be separately tested:

`python -m serial.tools.list_ports`
COM3
1 ports found

NanoVNA USB driver is STMicroelectronics Virtual COM Port 8/2/2013 1.4.0.0
