This is an upstream 3.7.7 stable regression, I think. Some of these
patches perhaps:
d7da098 USB: EHCI: fix for leaking isochronous data
caa891a USB: storage: optimize to match the Huawei USB storage devices
and support new switch command
08b4bfd USB: storage: Define a new macro for USB storage match rules
390077b usb: Using correct way to clear usb3.0 device's remote wakeup
feature.
93dffb7 USB: EHCI: fix bug in scheduling periodic split transfers
bf79379 USB: EHCI: fix timer bug affecting port resume
d01875f USB: EHCI: unlink one async QH at a time
269ef9f USB: EHCI: remove ASS/PSS polling timeout

Alan, any ideas?
