Question

when i connected the mp3 player with the device it didn't work out with me what shall i do

Answer 1

Was the cable already plugged in to the computer? Sometimes you need to plug the the player in to the cable first and then plug the cable in to the computer otherwise the computer won't recognize a new device.

Your USB port could also just be wonky and old and getting poor connectivity so try to jiggle it or unplug it and plug it back in.
