Hello Jasem,
I connected an eos40d with the canon driver and it correctly detects the 40 d.
I gave the info about de sensor and saved it in a profile.
Next I connected an eos750d and tried the canon driver, but the 750d was not recognized as was the case with the 40d.
When using the gphoto-driver, the 750d was as gphoto-camera detected.
My goal is reached ; I can save 2 eos cam's in profiles and the sensor-info is kept.
Why the 750d is not recognized by the canon-driver, I don't know but at least my problem concerning identifying 2 different eos-cams is solved.
