I turn on the options suggested by Felipe Balbi (CONFIG_PREEMPT and CONFIG_USB_DEBUG), along with applying David Brownell's patch and didn't get much more in /var/log/messages:

If I unplug and plug it in again, then sometimes it will connect. The successes and failures seem to come in runs, i.e. the chance of success or failure is influenced by a previous success or failure. Is there any other debugging that I can turn on to get more information from the driver?

Could you please set CONFIG_PREEMPT and CONFIG_USB_DEBUG on the HOST side... and send more verbose messages?? Another thing: Can you access the device anytime later??
