Hello,

   

  The function below has to return "CyFalse" instead of "CyTrue" to successfully transfer data.

   

CyBool_t
CyFxBulkLpApplnLPMRqtCB (
        CyU3PUsbLinkPowerMode link_mode)
{
    return CyFalse;
}   

   

  <Firmware API Guild> said :"The USB 3.0 host may request the FX3 device to switch the USB link to a low power state when the host has no more activity to perform." So, what does "no more activity" mean? Why is this request sent out from host? Thanks.
