IOUSBController
Abstract: Base class for USB hardware driver
Not many directly useful methods for USB device driver writers,
IOUSBDevice, IOUSBInterface and IOUSBPipe provide more useful abstractions.
The bulk of this class interfaces between IOKit and the low-level UIM, which is
based on the MacOS9 UIM.
