The USBIO Class Library (USBIOLIB) contains classes which provide
wrapper functions for all of the features supported by the USBIO
programming interface. Using these classes in an application is more
convenient than using the USBIO interface directly. The classes are
designed to be capable of being extended. In order to meet the
requirements of a particular application new classes may be derived
from the existing ones. The class library is provided fully in source code.
Figure E-4 shows the classes included in the USBIOLIB and their
relations.

The class CUsbIo implements the basic interface to the USBIO device
driver. It includes all functions that are related to an USBIO device
object. Thus, by using an instance of the CUsbIo class all operations
which do not require a pipe context can be performed.
The CUsbIo class supports device enumeration and an Open function
that is used to connect an instance of the class to an USBIO device
object. The handle that represents the connection is stored inside the
class instance. It is used for all subsequent requests to the device.
