mobile

So I just discovered my good old Galaxy S with a shattered screen (black screen). The touch is only working in the upper left part, cant see anything tho. It has a custom Rom. So the thing is, when I connect the phone to my PC, it makes that "device detected" sound, but I nothing shows up. I have tried everything, but probably USB debugging isnt enabled because it doesnt detect my phone in the ADB. Any solutions?
