    How to reduce CY8CKIT-033A current further ?

    sd547068172_1817156

      We have designed a product base on CY8CKIT-033A platform.We have re-designed the hardware with CY8C3446LTI-073, and worked in Apple device powered mode.

      But it can not pass the Apple's certification,because it draws too much current in low power mode.

      In the project Music_Creation, use APPLE_DEVICE_POWERED powered mode, uncomment HANDLE_USB_SUSPEND in Configuration.h.

      I debug the project, I found it can not  enter USB Suspend status.

       

      I have a few questions follow:

      1.In what conditions it will enter USB Suspend status?

      2.How to reduce the current further?
