What is Required and Where to Get Help
 Requirements
 Vendor ID—obtained from the USB Forum
 See following slide about how Silicon Labs can help
 Product ID—unique number identifying the product family of the
equipment
 Typically obtained from the USB Forum
 Serial Number—unique identifier for each specific equipment
developed under the PID
 Get help here
 USB Implementers Forum (USB-IF)
 www.usb.org
 USB 2.0 specification
 The USB class specific specifications
 USB Complete by Jan Axelson
 Special recognition needs to be given to Jan Axelson whereby
much of the material presented here is a direct reflection on the
excellent work from this reference
So we have completed the main portion of the training module that covers USB and
how it works. We have shown how the standard classes can benefit an application
by reduces development effort. Now that you understand USB we are going to give
a few tools that can abstract the entire USB operation to get a design
communicating via USB quickly. First, if you are going to be compliant to USB
and provide open functionality then you will have to obtain a VID from the USB
Implementer’s Forum. You can use the Silicon Labs VID and they can assign a PID
under their VID for customers to use. Also listed here are some useful guides to
learn USB in more detail. Thanks to Jan Axelson for the book “USB Complete” as
it has been an invaluable resource when putting this material together.
