Diagnose EHCI port resume

This is very bizarre.  Here's the important part of the log, leaving out
everything except for port 3:

[    0.971514] ehci_hcd 0000:00:1d.7: port 3 status1 1005
[    0.991544] ehci_hcd 0000:00:1d.7: port 3 status2 1085
[    0.991546] ehci_hcd 0000:00:1d.7: resume done

The status1 value should be 1085 and the status2 value should be 10c5, meaning
that the port was suspended at first but then the resume bit was turned on. 
Instead the port was unsuspended at first and then somehow it got suspended! 
That's why the scanner wasn't working; it was still suspended.

Try using this new patch and see if it makes any difference.
