    CY7C65642 bypassing #PWR and #OVR pins

    AlAh_4392861

      Hi, we are designing a new USB hub, and I have a question about the #PWR and #OVR pins. If our downstream devices are self powered, is there any problem with bypassing the #PWR and #OVR pins? I am planning to leave the #PWR pins floating and pulling the #OVR pins high with 10k resistors. Will there be any issues with enumeration if the downstream devices are powered up independently of the hub?

       

      Thank you
