There is an open source USB communication library available at http://www.icsharpcode.net/OpenSource/SharpUSBLib/default.aspx, its basically a wrapper around some WIN32 functions for USB comms. I've never used it personally, but it looks to be a place to start?

It's a .NET library, so can be referenced from a VB.NET project.

I have written an app (in MFC) that communicates over USB using Device Input and Output Control (IOCTL) API

Don't know about VB, but have a look at DeviceIoControl() etc...
