Force Feedback support not recognized on Granite Devices Simucube

Hi,

I own a Granite Devices Simucube force feedback wheel which I'd like to get working under Linux.
The current status is that if I use a tool to check/test the FFB, it tells me that the device does not support FFB.
I'm also using the device under Windows 7 and there it works without any special driver, so it should work with USB HID FFB.
In principle, it supports the following effects (see link below):
- constant force
- friction
- damping
- spring
- sine wave
- square wave
- sawtooth
- triangle

The device advertises as MCS, Granite Devices SimuCUBE with id 16d0:0d5a, I'll attach lsusb output.
Upon connection, the device is recognized and the output is:

I spent some time looking at the code and also other ffb code in usbhid, but since I'm not really familiar with C I have a hard time figuring out why it doesn't work out of the box and how to fix this, but I'd be happy to help implementing/debugging it.
For a start, it would be really nice to find out what is reported, what the report should look like and why it doesn't match.

Kind Regards,
Bernd
