Reply to Kontrol s2 keeps disconnecting: Please help!!

hi i just got an s2 and every minute or so it stops working and the USB icon on the s2 flashes. so i have to turn my s2 off and on again to reconnect it. if you know how to fix it that would be great.

P.S. when i inserted the USB into the controller it was very stiff to push in so it may just be my controller.

Thanks
