xHCI doorbells are fun. :)
I think I see the issue. Your host controller reports the Inactive
state after a USB disconnect. My host controllers go to the RxDetect
state on a disconnect.
The patches that went into 3.8 and the stable kernels to better handle
the Inactive state were not designed to handle a connected device going
to the Inactive state. I thought that would be a rare case, but
apparently it's not.
There was a further set of patches queued for 3.9 to deal with connected
devices going to the Inactive state, but they looked like they were too
big for stable:
d3b9d7a USB: Fix connected device switch to Inactive state.
a24a607 USB: Rip out recursive call on warm port reset.
2d4fa94 USB: Prepare for refactoring by adding extra udev checks.
0fe51aa USB: Don't use EHCI port sempahore for USB 3.0 hubs.
Can you retry with Greg's usb-next branch?
git clone git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/usb.git -b usb-next
If that fixes your problem, we should either get those additional
patches into 3.8 and the stable trees, or do a revert of the whole
series and just let 3.9 carry the full patchset.
