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.
Hi,
Make sure you remove any other rc.d scripts which kldload/kldunload ehci/ohci/uhci/... at suspend/resume.
Send complete dmesg showing a suspend/resume cycle.
Send output from usbconfig before and after suspend/resume.
Thank you.
Thanks for the response!
I have put the complete verbose dmesg from new boot, insert of usb memory, sleep, resume, (doesn't work), kldunload/kldload uhci/ehci, insert usb memory, (works again), and a log of the shell session covering the same here:

Both have annotations "==== <action>" for clarity.
Is it worthwhile to compile with USB_DEBUG and redo the above?
Hi,
SVN/CVS up or apply the following patch. Looks I forgot to MFC this:
It works!!! Connected devices are also reconnected properly on resume. Thanks very much indeed!
Bengt
