I tried out 8.2-STABLE (from Feb 3rd) on my IBM Thinkpad X40 to see
whether the updates to usb fixed the resume stall problem with
8.2-RELEASE. (The latter with the "gavin-usb-controller-patch" however
worked very well on this system!)
Unfortunately, 8.2-STABLE didn't improve. On the contrary, no usb
devices at all work after resume, so this is kind of a regression. I
tested with a couple of different versions of the usb system and
concluded that it is commit r229370 that makes the difference.
After resume, the console says:
uhub1: at usbus1, port 1, addr 1 (disconnected)
uhub2: at usbus2, port 1, addr 1 (disconnected)
uhub3: at usbus3, port 1, addr 1 (disconnected)
uhub0: at usbus0, port 1, addr 1 (disconnected)
What can I do to debug this further? It would be great to be able to
sort this for 8.3.
Some more info:
The code that executes the USB suspend and resume is located in:
All devices should be re-connected again at resume.
If you have USB audio devices, try suspend/resume w/o those plugged.
