* Name: stm32_otgfshost_initialize
|
|
*
|
|
* Description:
|
|
* Initialize USB host device controller hardware.
|
|
*
|
|
* Input Parameters:
|
|
* controller -- If the device supports more than USB host controller,
|
|
* then this identifies which controller is being initializeed.
|
|
* Normally, this is just zero.
|
|
*
|
|
* Returned Value:
|
|
* And instance of the USB host interface. The controlling task should
|
|
* use this interface to (1) call the wait() method to wait for a device
|
|
* to be connected, and (2) call the enumerate() method to bind the device
|
|
* to a class driver.
|
|
*
|
|
* Assumptions:
|
|
* - This function should called in the initialization sequence in order to
|
|
* initialize the USB device functionality.
|
|
* - Class drivers should be initialized prior to calling this function.
|
|
* Otherwise, there is a race condition if the device is already
|
|
* connected.
