How the Library Works

The USB Hub Host Client Driver does not contain any application callable functions. The only step that the application code must implement is to enable USB Host Layer Hub support and to provision the USB Hub Host Client Driver in the TPL table. 

The USB Host Layer enables Hub Support when the USB_HOST_HUB_SUPPORT_ENABLE configuration macro is defined in system_config.h. Refer to the Configuring the Library section of the USB Host Layer Library Help Topic for more information.
