I am trying to use USB OTG as a host. I have to enable PA9 pin which is the VBUS. I tried everything but could not get 5V only 3.3V. What I am missing?
GPIO_InitStructure.GPIO_Pin = HOST_POWERSW_VBUS;
GPIO_InitStructure.GPIO_Speed = GPIO_Speed_50MHz;
GPIO_InitStructure.GPIO_Mode = GPIO_Mode_Out_PP;
/* By Default, DISABLE is needed on output of the Power Switch */
