I don't know about tracking this down, but for testing purposes you can
reproduce these conditions without actually unplugging and replugging the
device.  All you have to do is go into the /sys/bus/usb/drivers/usb_storage
directory.  In there, you'll see a file representing each usb-storage device in
your system, with names like "2-1.2:1.0".

To imitate an unplug, write the corresponding file name to the "unbind" file. 
To imitate a replug, write the file name to the "bind" file.  For example:

   echo -n 2-1.2:1.0 >unbind
   echo -n 2-1.2:1.0 >bind

This can easily be automated in a shell-script loop, which should speed up your
testing.
