Hi Kevin.
The patch from this email was identical to the patch I sent the other
day.
I can not confirm with that. For your reference I have added the patch you sent
on 11.12.2014 19:46:
It looks like the hub is found, but responds with a "stall" error on
the get_hub_desc() request. Looks like usb3 hubs use a different
descriptor id. You could try the patch below - it's a lot of guess
work though.

This is way different from your latest patch Paul mentioned.
Did I missed something or wath your first patch not the right one?

Super speed hubs (usb3 spec) have specific initialization
requirements. Add the code necessary to detect and initialize these
hubs.
Could you please add how you tested this? For example the board, the hub
and what you booted from it for example.
I used an Anker 4 port usb3.0 hub, which I tested with an ADATA 16GB
usb3.0 flash drive on both my Acer c720 and Asrock e350m1-usb3.
If you're requesting that info be in the commit message - I don't
think that level of detail is required there.
