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.

noteNote
This test applies to USB 3.0 hubs only. The test automatically passes for non-SuperSpeed capable hubs.
