Beware of cheap underperforming clones
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.

Windows 10 cannot connect to Device xavna_read_autosweep failed: Resource deadlock avoided

Hey getting the above error when I try and connect to the VNA via NanoVNA-QT. The saver application seems to work fine. I have tried reinstalling the driver to no avail. Also I read on a youtube post to disable "data validation" in the device driver, I think) but cannot see where to do this.
Any help please?
Am I looking in the wrong place to disable "data validation" or what do I need to do?
With thanks
