330ZI connected but not detected

Dear community,

I can't figure out why I can't connect anymore to imu. When I run openimu command in vscode It find tne connected device (openimu 330ZI EVK) but can't connect to it.
With the previous installation of Ubuntu I had no problems.
When a couple of days ago I had to reinstall Ubuntu 16.04 no way to connect to imu.
I followed all insttrucions to get it work.
Download and install vscode.
Built from source python-openimu from Aceinna repo of github
I also gave rights to USB.
Moreover I rebuild factory data on EEPROM with ST-link following the tutorial on readthedocs (Warnign before starting development).
I'm starting to think that It could be a python issue. Can anyone explain me steps to follow and wich python version I need?

Thanks

Matteo

pls supply xxx.log file in your logger folder of python-openimu(develop branch), when you cannot connect it after python driver running some time.

thanks a lot for your information shared
