USb-if certification
Compliant USB products ensure interoperability and consumer satisfaction. USB-IF aims to make all certified USB cables, chargers and other devices easily identifiable. USB-IF reminds you to purchase compliant products from trusted sources that display USB-IF certified logos on packaging, in product briefs or on the cable or device itself.
Products that successfully complete USB-IF certification and sign a logo license agreement can use the certified USB marks to identify the performance and power protocols supported.
