Understood.
What version of the kernel are you using?
The previous output was from a 3.3.8 kernel w/ commit 50ce5c0683aa83eb161624ea89daa5a9eee0c2ce applied.
You should build a test kernel with CONFIG_USB_DEBUG enabled. When the problem occurs, post the output from the "dmesg" command -- not the contents of the system log file.
I have already enabled CONFIG_USB_DEBUG, as well as a large number of other debug options attempting to get something more than the previous back-trace. I have also enabled CONFIG_OHCI_VERBOSE_DEBUG (overkill?) on a few systems in hopes that something useful would be made more self-evident.
This is useless. We need to see what happens when the problem occurs, not 2 minutes later.
Unfortunately the previous back-trace is the only data that shows up. Even with CONFIG_USB_DEBUG there isn't anything actively arriving in the kernel log buffer as reported by dmesg.
