Can’t connect Zen Mozaic EZ300 mp3 player to my pc

Hello,
I want to connect Zen mozaic EZ300 mp3 player to my pc. When I go to plug in my Zen Mozaic EZ300 mp3 it’s showing ..’Conecting…’, ’Conecting…’
But it is not connected actually. I can’t charge it from my pc also, actually it is not recognized device. Is something wrong with the laptop?…or is something wrong with my Zen Mozaic EZ300 mp3 player? How to recover?
Thank you
