As of 2022 there are many badly performing clones on the market. V2/3GHz NanoVNA uses parts like ADF4350 and AD8342 which are costly and clones have been cutting costs by using salvaged or reject parts.
See official store and look for V2 Plus4/V2 Plus4 Pro versions only to avoid getting a bad clone. We have stopped selling V2.2 versions since October 2020, so all V2 hardware that are not Plus or Plus4 are not made by us and we can not guarantee performance.
Hello
I tried to use V2 with PC, but i cant install drivers.
Device hardware id is incorrect: VID_0000&PID_0002
Driver is not installed.
How to solve this?
Maybe i bought a clone device?
Hello
Did you read user manual? Did you check the home page for software?
Try:
https://github.com/nanovna/NanoVNA-QT/releases
On Windows, please run CypressDriverInstaller_1.exe to install the USB-CDC driver.
Hello
of course i did it. I tried to manual update driver after. Nothing. I suppose the device does not have correct device id and windows cant recognize wich driver should be used.
Also i tried manual install driver by Zadig. Zadig reports error that device with this id has already used. Please see the screen usb ID section. I think the problem is the device flashed icorrectly with no hardware ID.
screen
Try in another pc, clear device from registry, uninstall old drivers.

I did it, the result is the same
Is there other interface, to reflash the device? Non usb, for example SPI or ISP?
Or is there a way to change VID/PID?
If you look at the photos on this page: https://groups.io/g/NanoVNAV2/topic/v2_photos/74581398?p=,,,20,0,0,0::recentpostdate%2Fsticky,,,20,2,60,74581398
the first photo shows a debug port on the edge of the card. A standard jlink debugger will connect to this (as will others). The debugger can easily reprogram the bootstrapper. You can search on amazon for jlink debugger and find a bunch.

Does this help me?

Yes, exactly that kind of thing. I can't guarantee you can find software for it since I don't know how compatible, but the debug port is very simple. The cheapest such devices on Amazon are about $12.

Thanks
Also
Is there way to force win10 to work with my device that have such VID_0000&PID_0002?
I found the problem!
There was short circuit between d+ and d-.
I resoldered usb socket and problem has gone.
Thanks for all.
