------ i connected xHCI root hub -->HS hub--> the same 2.0 device , it works fine.

When a SS hub is connected to EHCI, it just works like a HS hub. No 
address device command is issued.

Can you post the output of lsusb -vvvv and lspci -vvnn?

And what occurs with the following two scnearios:

1. xHCI root hub --- SS hub --- some other USB 2.0 devices
2. xHCI root hub --- some other SS hub or HS hub  --- the same USB2.0 device

Thanks,
Andiry
