Returns the amount of bandwidth available on the bus for allocation to periodic pipes. If the device is a high or super speed device, it will be the number of bytes per microframe (125 �secs). If it is a full speed device, it will be the number of bytes per frame (1ms)

This function is useful for determining the correct AltInterface setting as well as for using SetPipePolicy. The interface does not have to be open to use this function. Availability: This function is only available with IOUSBDeviceInterface500 and above.

Parameter self: Pointer to the IOUSBDeviceInterface.

Parameter bandwidth: Pointer to UInt32 to hold the amount of bandwidth available (in bytes per frame or microframe).

Returns: Returns kIOReturnSuccess if successful, kIOReturnNoDevice if there is no connection to an IOService.
