I have tried installing every USB driver I can find for the nanoVNA but none of them makes the nanoVNA appear in the list of USB devices.
Have installed Cypress driver and 64 bit ST virtual COM port app.
No new COM ports appear when VNA is connected nor when virtual COM port app installed.
Device manager shows new 'Unknown USB device (device descriptor request failed)' when VNA-H is connected and powered up. Cable appears to be good since Device manager sees the VNA.
Tried several apps, VNA-QT, nanoVNA sharp 1.03, nanoVNAsaver, none will connect.
PC is Win 10.
Thanks for your help.
