{sigh} I'm hating that driver right now...

There are a number of pending bluetooth patches for that driver that fix
a number of different bugs, so I'm leary of trying to see if this is a
different one or not at this point in time. Care to apply all of the
bluetooth patches and if this still happens, can you report it to the
linux-usb-devel and bluez-devel mailing lists?

CONFIG_DEBUG_DRIVER might be good to set, and then we can see if we are
not trying to remove the same device twice for some odd reason. If you
do duplicate this, please include all of the debug log entries that
happen from when you unplug the device.

Also CONFIG_USB_DEBUG might help out.
