Hello Stevop123,
I am sorry for the delay on coming back to you.
Based on our research, Windows 7 doesn’t support kernel debug over xHCI. This is a OS debug limitation. In this case there are two options for you:
- Install Windows 8 on the system to use xHCI debug.
- Un-install xHCI driver on Win 7 so USB port will be routed back to the EHCI controller. You then can connect cable to port 1 or 9 for kernel debug.
