USB is quiet different from parallel ports You can not access it as a "port", instead you will need to communicated with the driver of a particular device. Therefore CreateFile can't be used to get an usb handle.

Although there are exceptions when you can use CreateFile:
When dealing with USB modems. Then all you need is to get the handle of an appropriate COM port and use it as a regular file.
Or when communicating with HID devices (mouse, keyboard). CreateFile then ca be used along some other function to receive/send control  data structures for manipulating the device (e.g. set current mouse cursor position)
