To open a handle to a USB device, you have to use the SetupDixxx APIs to enumerate and find the device.
Here is an example for enumerating USB devices - http://www.velleman.eu/images/tmp/usbfind.c[^]

Once the correct VID/PID pair is found, you can use the DevIntfDetailData->DevicePath in a call to CreateFile.
