In order to display a USB certified logo on the end product or packaging, the

designers will have to undergo compliance testing. The USB implementer’s forum

has a list of approved compliance testing vendors. Once a product passes, the

vendor then has the product listed.

The forum also assigns a vendor ID (or VID) so that the designer can assign the

product with a unique ID number.

You can contact silicon labs for assistance.
