# 3.2.4.39 USB_HOST_BUS_ALL Macro

## C

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

## Summary

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.

## Remarks

None.
