I can't tell from these messages exactly what's wrong. In fact, it looks
like the third line should have been printed _before_ the second line.
What do you get in the system log if you turn on CONFIG_USB_DEBUG?

actually i haven't debug enabled.
I can't tell what's wrong without the debugging messages.
