I had to remove the driver, and reinstall it. I was able to get it to load. I found NanoVNA v1,01. which works, but not stable.
Is there a way to tell what rev the firmware is? I got mine on Monday, but the eBay seller I got it from sent only the unit and the cal kit

I just received my Nano yesterday. Using it standalone in the 10-20 MHz region measuring the S11 of an antenna, I am pleased to find that the smith chart matches my HP 8752.
Much more testing to follow.
However, I am unable to connect via the USB/serial link. I pulled the file: nanovna-cdc-acm.inf from the zip file from the banggood site and direct windows to that file when attempting to update the "ChiBios/RT Virtual COM Port". However, windows(win 7 64bit) complains:
"Windows found driver software for your device but encountered an error while attempting install it.
NanoVNA
The system cannot find the file specified."
There appear to be references to other files in the .inf file. Does anyone have any hints on what other files I may need to get this up and running?
Thanks!
