Brake pedal not recognized - Logitech G920 Steering Wheel

Hello everyone,

After some research, I can't find anything that corresponds to my problem, so I'm turning to you.

I recently acquired a G920 to play on Xbox. Bought second-hand, for once I didn't test it beforehand with the seller and, of course, I'm encountering a problem... Indeed, the brake pedal on the pedal set is only barely recognized, just the end of the travel.

For example, on GHub or on Assetto Corsa, I'm at full pedal every time: 

Of course, the previous owner assures me that he never had any issues but there's no way to verify.

I should mention that I'm having the problem with all games (Assetto Corsa Competizione, FH5, Project Cars…) on Xbox and PC.

Does anyone have any idea?

Thank you !!
