It seems that you are just seeing a regular event device. What have you done so far? You might try for example Using the Input Subsystem article on Linux Journal.
What you should try at first should probably be:
/* how many bytes were read */
size_t rb;
/* the events (up to 64 at once) */
struct input_event ev[64];
rb=read(fd,ev,sizeof(struct input_event)*64);
if (rb < (int) sizeof(struct input_event)) {
perror("evtest: short read");
exit (1);
}
for (yalv = 0;
yalv < (int) (rb / sizeof(struct input_event));
yalv++)
{
//if (EV_KEY == ev[yalv].type)
printf("%ld.%06ld ",
ev[yalv].time.tv_sec,
ev[yalv].time.tv_usec,
printf("type %d code %d value %d\n",
ev[yalv].type,
ev[yalv].code, ev[yalv].value);
}
Then you should pay attention, what event types are being emitted, and then work with them further.
