USB 2.0 Compliance Testing
To complement the specification and enable measurement of compliance products, the USB-IF has instituted a Compliance Program that provides reasonable measures of acceptability. Products which have passed compliance testing have the rights to use the USB-IF certified logo, and offer the consumer a degree of certainty that this product will function as expected, with no undesired surprises. Please check www.usb.org/developers/compliance for more information on compliance testing. Recently a number of independent test labs have recently been certified to test all USB devices at all speeds, as well as full-speed (so-called "1.1") hosts and hubs. A complete discussion of the test labs and their capabilities may be found at www.usb.org/developers/compliance/labs.html. Hi-speed hosts, hubs, and devices using silicon that has not been certified are still tested at the Peripheral Integration Lab. Contact for details and scheduling information.
