Alan, When the system fails, ps shows khubd with a status of DW. I have verified that the change makes it to hub_irq, but for whatever reason the hubd thread is in uninterruptible sleep state. I can reproduce the failure by cat'ing /proc/bus/usb/devices while performing a mount on the usbdrive. Below is a log (not much info) with some additional debug statements from my hcd. The "rh change 2 status 0" statement is from hub_status_data function. Thanks for your help.
