Wheel range of certain Logitech wheels - namely Driving Force GT, Driving Force
Pro, G25 and G27 can be adjusted. Minimu is 40 degrees, maximum 900. DFGT, G25
and G27 all use a common command, DFP uses another one. Range can be set from
userspace by writing to
"/sys/module/hid_logitech/drivers/hid:logitech/<dev>range". The driver use list
to store range of each connected wheel; it's not possible to use driver_data in
hid_device struct as it's already b hig-lg driver.

http://wiibrew.org/wiki/Logitech_USB_steering_wheel
This patch relies on previous patch:
"Don't Send Feature Reports on Interrupt Endpoint"
Logitech as produce a very similar wheel for the PS2/PS3, it is expected that
this patch could also support the PS2/PS3 wheel if the USB ID's are added and
(if required) the HID descriptor is modified.
