USB FS over BLUETOOTH

Hi,

i have this radio (::Sunstech::) with usb interface, where i put usb stick and reproduce mp3 music, nothing new...

now i ask, there is something that i could connect to this usb and simulate a remote FS over bluethoot in a computer. I want hear mp3 from PC in this radio, using "something" that when this radio make a directory dir, this return (over bluetooth) the remote list...

This is a general question, and the posibility to implement with arduino...
