I want to implement some custom functions of my mouse (Madcatz RAT5) in
Linux, e.g custom DPI-values. As this requires writing over USB to the
firmware of the mouse I was thinking of writing a module to accomplish
this. However I don't want to reimplement a whole mouse-driver,so I
wanted to ask if there is a possibility of binding the device to 2
modules or having my module extend usbhid, so that my module would only
be used to perform these custom operations while usbhid stays in charge
of the whole "mouse business".
