Logitech DFGT issue.

[BkS]

But I think you could still use it as a template. It looks like it is mostly about adding the device id.

in drivers/hid/hid-core.c add:
{ HID_USB_DEVICE(USB_VENDOR_ID_LOGITECH, USB_DEVICE_ID_LOGITECH_DFGT_WHEEL) },

in drivers/hid/hid-ids.h add:
#define USB_DEVICE_ID_LOGITECH_DFGT_WHEEL // DFGT_ID_HERE

in /drivers/hid/hid-lg.c add:
{ HID_USB_DEVICE(USB_VENDOR_ID_LOGITECH, USB_DEVICE_ID_LOGITECH_DFGT_WHEEL), .driver_data = LG_FF },

Maybe you should contact Michael Bauer (LTWheelConf creator). As he has been working on DFP support:

I have my wheel working with LTWheelConf, I just have no FFB and trying to drift without FFB is like a dog without it's nose. Just useless. I'll have a deeper look into the HID thing but I am no expert when it comes to CLI.
