The advantages of connecting a device to a USB 2.0 hub are as follows:
We recommended this connection for regular USB devices.
This connection is required for the USB Selective Suspend test. For more information, see USB Internal Device Idle Test - Compat.
This connection forces the Enhanced Host Controller Interface (EHCI) high-speed controller to enumerate low-speed and full-speed devices.

Devices that have embedded hubs must be directly connected for certification tests.
We do not recommend multi-TT (transaction translator) hubs for certification testing.
When you are testing a device that has an embedded high-speed hub, attach the device directly to the system for all tests.
