Problem with Logitech SpaceNavigator

Hi,

I've a problem with some SpaceNavigator devices with a newer firmware 
(4.31). The problem is that the fixup for the EV_REL/EV_ABS 
(LG_RDESC_REL_ABS) is not applied for the new firmware because the 
report_descriptor is different (see attachments). It looks like the 
checked and modified bytes are no longer at offset 32/33 and 49/50 but 
at 36/37 and 53/54.
Is my assumption correct and is it possible to get this into hid-lg.c ?

Thx,
Christian Ehrlicher
