You have the USB multi-threaded device probing config option
(CONFIG_USB_MULTITHREAD_PROBE) enabled, right?
Yes, I have.
Does disabling it fix this problem?
I'll disable it and try to reproduce the problem.
That option has been reworked by Alan Stern, and I need to intregate it
into my tree soon. This is the first report of a problem with the
current stuff, I wonder why.
Can you send the output of /sys/proc/bus/usb/devices with the same
devices plugged in on a different, no oopsing kernel?
cat /proc/bus/usb/devices
