Hi,
I think there is an issue with the reset-resume mechanism during USB runtime
resume, leaving the interfaces suspended forever.
- Context:
Android platform, running a 3.13 + Google AOSP patches kernel.

suspend en
other solution found (logical disconnect, reset_resume mandatory...). But
I think this dead end should be fixed.

But should be completed with an other patch or new patchset for the btusb
driver (at least).

usb_unbind_and_rebind_marked_interfaces.
It works great with the combination of this two fixes. I even reproduced the
btusb runtime-resume
hardware issue which is now handled correctly, interfaces are unbind/rebind.
