Sorry man, impossible, you would have to install a homemade headphone input.
Here are some instructions,
1.Get an old mp3 player
2.Remove the Headphones Input
3.With the headphone Input attach to Pendrive
4.Get hammer and smash until both are completly united
5.Press play..Oh wait Pendrives dont have Play button..
6.Repeat Step 1 Through 5 again, until you have reached Device Desired.
