Subject: Re: [PATCH 1/1] usb,uhci: add a new tag for virtual uhci devices

There was a problem, the warning "Controller not stopped yet".
And your last patch for this problem does a wrong thing:
It prevents all HP uhci devices from auto-stop, which make HP uhci 
devices waste more
power.
This is another new problem.

I think this should be corrected, so I want to apply it.

Thanks
