WinUsb interface in Windows 7

[robert.jenkins]

My student are trying to use Jan Axelson's downloaded vbasic project (winusb_vb) for devices with the WinUsb driver in Windows 7.  We are getting errors whereby certain api calls are not found in the specified dll libraries. In particular "CreateFile" not found in "kernel32.dll", and "SetupDiGetClassDevs" not found in "setupapi.dll".
Can anyone shed light on this problem?

The error occurs on building the project? What is the exact error message? Does the error occur on the first function called in each DLL?
