The detection requires the opening of the file / dev and thus the permissions to do it. You must be part of a group with the necessary permissions. The most reliable solution for listing i2c and spi buses is udev. It is therefore necessary to switch the detection of i2c and spi buses on udev.
Fixe by v0.3.20
