Refer to the Win32 API documentation for the syntax and the
parameters of the functions SetupDiXxx, CreateFile,
DeviceIoControl, ReadFile, WriteFile, CloseHandle. The file
handle can be opened with the FILE_FLAG_OVERLAPPED flag if
asynchronous behaviour is required.
More code samples that show the usage of the USBIO programming
interface can be found in the USBIO Class Library (USBIOLIB), the
USBIO demo application (USBIOAPP), and the simple console
applications ReaderCpp and ReadPipe.
