That sure makes for some mystery, Gabriel! Why do you use a pseudonym?

I can confirm that currently the only way to exit USB mode is to toggle the power switch. I'll look into adding a register to allow changing modes.
The USB interface always outputs raw, uncalibrated values, as is in the user manual. The reason is the assumption that the PC software always has superior calibration routines (e.g. supporting arbitrary cal kit parameters) and it is far less error prone if you can't be confused whether you are reading calibrated or uncalibrate values.
The VNA logic in the firmware was written from scratch, and we haven't yet implemented calibration interpolation (it wasn't removed, just never implemented). Personally I've not had good experience with using interpolation on other VNAs that support it; I've found it to give wrong results every time unless you have an insanely high number of sweep points (1000). However if there is popular demand we can go and implement interpolation.
