The certification tests for USB peripheral devices can be divided into three categories. The first is electrical characteristics testing to verify the signal quality of the product under different application architectures. This is followed by a functional test to check higher-level product details, such as the level of support required by the standard and device enumeration capabilities. Finally, the product interoperability test is used to determine the interaction between the product under test and other USB devices.
