This looks really strange, I can't get myself to stop thinking that you forgot
the <> around this (I know it's a string). I don't like these defines.

Why not name the nodes something useful?
If you name it tusb3-hub-reset you can skip the comment.

Same here, any suggestions? Except function tables in driver :-)
