  Hi,

  My device is a USB based keyboard and  am running the USB Topology Compatibility Test, then applies all those topologies manually.

  But I got failed error only on this topology, EHCI-> DUT. My motherboard having internal HS hub. Due to that not able access the port and the test got failed.

  1. If any one facing this problem pls help how can I pass this test

  2. Suggest some EHCI and xHCI root port accessible mother board.
