Do we really need the HID_TYPE_KEYBOARD at all? It's not used anywhere in 
the code. I'd propose to add it when it is actually needed. I.e. have the 
enum contain something like HID_TYPE_MOUSE HID_TYPE_OTHER for now, and add 
whatever will become necessary in the future, what do you think?

I think a more descriptive comment would be appropriate here. It might not 
be obvious on the first sight why this needs to be done separately from 
the generic hid_blacklist. I.e. something like

/** 
 * There are composite devices for which we want to ignore only a certain
 * interface. This is a list of devices for which only the mouse interface 
 * will be ignored.
 */

maybe?

Thanks,
