from http://home.t-online.de/home/gunther.mayer/gm_psauxprint-0.01.c :

char a4tech_id[]={ 0xf3,200, 0xf3,100, 0xf3,80, 0xf3,60, 0xf3,40, 0xf3,20};

if(a4tech) {
sendbuf(fd,f,a4tech_id,12);
        buf[0]=0xf2;
        write(fd,&buf,1);
        b=consumefa(f);
        printf("a4tech ID(f2) is %x\n",b);

        if(b==6 || b==8) printf("AUTODETECT: a4tech\n");
        // b=6: spiffy gyro-mouse "8D Profi-Mouse Point Stick"
        // b=8: boeder Smartmouse Pro (4Button, 2Scrollwheel, 520dpi) PSM_4DPLUS_ID MOUSE_MODEL_4DPLUS
