Samsung Yp U3

My Samsung YP-U3 won't let me put music on it, help?

for the past few months now my samsung yp-u3 will plug into the computer, but it will say 'disconnected'. even though it says disconnected it still recharges, in other words i cant put or take any music on/off it. :(
could it be broken? i dont

Know an answer?

dont quite know but

you may for one need to install a program
or either your computer or phone wont accept each other's connection

I dont really know how they work, but thats what i gathered from my other phones.
