My test program used poll/select on edge successfully. But I could not test the raising or falling feature actually, as my input is bouncing. So, it doesn't matter if I set both/raising/falling in edge, due to my inputs the effect is the same. Any input event will end in several raising and falling interrupts events. I hope I could make this more clear.
