USB-IF Qualification by Similarity Program

The USB-IF offers a Qualification by Similarity program to companies that have USB-IF certified products. The QbS program enables a new USB product to be certified based on its similarity to a fully tested and certified USB product. The purpose of the QbS program is to speed time-to-market and to minimize certification costs. It is not intended to eliminate the requirement that a product actually pass USB-IF compliance tests. For more information regarding the USB-IF Qualification by Similarity program, please see the QbS Introduction webpage.

The USB-IF Certification Program only tests and certifies a specific name, model and revision number of a USB product. A product that has a slightly different name, model number or revision number is not considered certified. In addition, the USB-IF does not allow the use of variables in the product's name, model number or revision number. The Qualification by Similarity program enables a product with different names, model numbers or revision numbers to be certifed provided the product is, effectively, the same.

The USB-IF accepts Qualification by Similarity requests via online forms. Please allow up to 28 business days for processing. The forms should work using modern Internet Explorer or Firefox browsers. For more information please see the Form Help Page.
