USB Host Bus All 

This constant defines the value that should be passed to the USB_HOST_BusSuspend(), USB_HOST_BusResume() and USB_HOST_IsBusSuspended() function if all the USB segments must be addressed. Passing this constant to these functions will cause Suspend and Resume operation to affect all the USB segments and hence affect all connected devices.

#define USB_HOST_BUS_ALL ((USB_HOST_BUS)(0xFF))
