Sorry for top posting. I consider a problem, when an arbitrary device could perform some kind of request to your system.... not just the fact of writing to a /dev file.... if later that content becomes inoffensive if something else does not interpret it and then does something consequently..... that's what I was wondering, if you an experts of this kind of communication device or the own protocol, could know if by the fact of being listening (because the module load) in irda without later having configured nothing conscientiously (at least) to act with that input, could cause any kind of problem to a computer.... Just that... not just the fact of receiving input... a wifi device receives input constantly.... but later it connects where you say to wpa_supplicant for instance.... so I have just had loaded the hid-generic kernel module... but nothing else... just if that could become dangerous if someone could... you know... or if you recommend reinstalling the os...
