## Variables
volatile U16 | g_usb_event
| 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).
U8 | g_usb_mode
| Public : (U8) g_usb_mode Used in dual role application (both device/host) to store the current mode the usb controller is operating /.
U8 | remote_wakeup_feature
| Public : (U8) remote_wakeup_feature Store a host request for remote wake up (set feature received) /.
volatile U8 | private_sof_counter
| Private : (U8) private_sof_counter Incremented by host SOF interrupt subroutime This counter is used to detect timeout in host requests.
volatile U8 | otg_features_supported
