Its not a big problem, but a little strange issue. I have a DFP and a cheap controller with vibration. No problem with DFP alone, but when they are both connected to USB, LFS seems to send FFeedback to the pad, so it buzzes and theres no FF in the wheel.

No much problem, but since LFS and PES6 are all the games i play, i rather have them connected at the same time.
