@EA_rephii I didn't try the T300 basic wheel as I do not have it anymore, and the pedals are the base T300 RS GT pedals so they are also the only ones I own.
I did a full reinstall of all drivers, firmwares etc which ended up working (all ffb features as well as telemetry options work).
This is a bit of an head scratcher to me as I did that previously already which yielded no result.
It could be that a full installation from scratch now works because of the newest drivers / firmwares while the previous ones weren't working even with a installation from scratch.
Side note : I did not have to switch from advanced mode to normal to have my wheel work.
