Logitech Formula Force EX Wheel on Linux
On my birthday, my friends bought me a Logitech Formula Force EX Feedback Wheel. After playing with it a lot in Windows, I decided to make it work on Linux. The force feedback part didn’t work out of the box. I managed to make it work with the usb-hid driver after I added it’s usb id to it. You can find the patch against kernel 2.6.18 here.
- Copy the file to your kernel source root directory.
- Apply the patch:
patch -p1 <logitech_formula_force_ex_ff.patch
- Recompile the usbhid module
- Reload the usbhid module.
- Have fun testing it with ffutils.
(Only the constant force effect works as this is the only effect currently implemented in the driver).
