Variables
volatile uint16_t	g_usb_event =0
	Public : U16 g_usb_event usb_connected is used to store USB events detected upon USB general interrupt subroutine Its value is managed by the following macros (See usb_task.h file) Usb_send_event(x) Usb_ack_event(x) Usb_clear_all_event() Is_usb_event(x) Is_not_usb_event(x)

bit	usb_connected
	Public : (bit) usb_connected usb_connected is set to TRUE when VBUS has been detected usb_connected is set to FALSE otherwise Used with USB_DEVICE_FEATURE == ENABLED only /.

U8	usb_configuration_nb
	Public : (U8) usb_configuration_nb Store the number of the USB configuration used by the USB device when its value is different from zero, it means the device mode is enumerated Used with USB_DEVICE_FEATURE == ENABLED only /.

Detailed Description

This file manages the USB task either device/host or both.

This file manages the USB storage.

  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

Definition in file usb_task.c.
