USB 3.0 Hub Enumeration Stress
This test verifies that a USB 3.0 hub does not turn off SuperSpeed termination on downstream ports, when overcurrent or port-reset events occur. The test stresses enumeration of the hub under test and verifies that the hub, as well as a downstream peripheral, enumerate properly. The downstream peripheral must remain on the SuperSpeed bus and not switch to high speed.
