Charging problem CoreInk

  • Hello!
    I have a problem with my CoreInk: I cannot charge the battery through USB and I cannot upload my code in the CoreInk powered through USB.
    If I want to upload a code in CoreInk with IDE Arduino, I need to plug the battery in it and the battery doesn't charge with USB. To charge the battery, I need to plug another supply by a 5V IN below the CoreInk. The LED of charge is OFF when I plug USB but ON when I supply with below port. Does someone have an idea of why I have this problem, and what is the cause of that?
    Thanks in advance

  • have you tried to use different usb port/cable?
