Message-ID: To: kernelnewbies@lists.kernelnewbies.org List-Id: kernelnewbies.lists.kernelnewbies.org Hi everyone, 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". Thanks Pol
