Hi Paul,
I'm not following as to why you are patching the descriptor for the DFP,
my understanding is that this is fully supported at the moment (as
USB_DEVICE_ID_LOGITECH_DFP_WHEEL in the line after your patch).

Perhaps you have a different revision. Can you please forward a 'lsusb
-vv' to we can compare.

I have attached the one from my DPF.
