*
|
|
* \brief
|
|
* This file manages the USB task either device/host or both.
|
|
*
|
|
* The USB task selects the correct USB task (usb_device task or usb_host task
|
|
* to be executed depending on the current mode available.
|
|
*
|
|
* According to USB_DEVICE_FEATURE and USB_HOST_FEATURE value (located in conf_usb.h file)
|
|
* The usb_task can be configured to support USB DEVICE mode or USB Host mode or both
|
|
* for a dual role device application.
|
|
*
|
|
* This module also contains the general USB interrupt subroutine. This subroutine is used
|
|
* to detect asynchronous USB events.
|
|
*
|
|
* Note:
|
|
* - The usb_task belongs to the scheduler, the usb_device_task and usb_host do not, they are called
|
|
* from the general usb_task
|
|
* - See conf_usb.h file for more details about the configuration of this module
