    MCU Deep Sleep enabling USB host function.


      I am trying to let CYW43907 (WICED-Studio-6.1) sleep during enabling USB host function.

      I uses test sample program, <WICED_Studio>/apps/test/powersave/powersave.c.

      To make MCU in DeepSleep mode, I called wiced_usb_host_init in this sample program, but it doesn't go to DeepSleep mode.

      When execute mcu_powersave_sleep 1 3000, "Refuse to sleep due to WLAN resources are still requested" is displayed and doesn't go to sleep.


      Does anyone have any suggestion for this issue ?

      Or CYW43907 can't go to DeepSleep mode when enabling USB host ?
