The uC/OS BSP can configure a USB port automatically as a host. To do so select it in the ucos configuration panel specifying that the port should be used a host instead of a device.

 

 

Initialization

Since the function of a USB must be defined before enumeration the uC/OS BSP startup code will only configure and interface but won't start it. Once fully configured a USB interface can be started by calling USBD_DevStart().
