Hello Rune-
First, thanks for the very useful NanoVNA-Saver application!
Earlier in this thread you mentioned setting the data rate at 115200 bps. This is 2nd hand information- somewhat anecdotal- but apparently plugging multiple devices (mouse, keyboard, etc.) into a USB hub can alter/decrease the data rate for other devices on the hub. I wonder if this can explain any of the cases of reported NanoVNA data loss. I first heard of this over at the SDR-Radio Groups.io list. I realize that 115200 is 'quite slow' by nominal USB standards.
