I was cleaning out my harddrive when i found some pictures of my old FFGP wheel:

As you can see, the chip that drives the force feedback motor is gone.
My powerbrick that came with the wheel was broken, so i took another brick with the same voltage, but i accidently swapped + and -, so it went *poof*.
I removed the chip, but couldn't find a replacement, there was virtually no chip left so i couldn't read the text on top.
Amazingly, the wheel still works fine (well, obviously not the FFB). So it might just work if i replace the burned chip.

Can anyone tell me what chip it is? I tried Logitech support, but they can't help me. I suspect it's a bunch of FETs in a smd dip package, nothing special.

might be another revision of the board :) Thanks for the picture, the chip seems to be a pwm motor driver from Alegro (type A3953) :thumb:
