* Name: kinetis_usbhost_vbusdrive

* provided by each platform that implements the OHCI or EHCI host

* interface
|

|
* rhport - Selects root hub port to be powered host interface. Since the
|
|
* KINETIS has only a downstream port, zero is the only possible value for
|
|
* this parameter.
|
|
* enable - true: enable VBUS power; false: disable VBUS power
|
|
*
|
|
* Returned Value:
|
|
* None

* condition is detected.

|

|
|
* arg - The argument that will accompany the interrupt
|
|
*
|
|
* Returned Value:
|
|

|
|
* Name: kinetis_ehci_initialize
|
|
*
|
|
* Description:
|
|
* Initialize USB EHCI host controller hardware.
|
|
*
|
|
* Input Parameters:
|
|
* controller -- If the device supports more than one EHCI interface, then
|
|
* this identifies which controller is being initialized. 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.
