Using USB30CV
If testing a hub downstream-facing port (DFP), the upstream port of the hub must be connected
to a host system with USB30CV installed. USB30CV is an application provided by the USB-IF
(
www.usb.org
) that is used for link layer and hub testing, as well as other compliance test areas
outside the scope of this document.
USB30CV will control some of the Link Layer tests in conjunction with Examiner (as shown in
the figure below), and will also provide VBUS to the hub, which is required for all Link Layer
tests on a hub downstream port.
If testing a host port, please ensure USB3.0CV is loaded on the host under test as USB3.0CV
will control some of the Link Layer tests in conjunction with Examiner.
To download USB30CV, follow this link
