usb-serial can not get unloaded if there is a reference held on a sysfs
file owned by it, or if a user has a port open.  This is due to the
module reference counting logic in sysfs attributes, and in the module
reference count stuff in the usb-serial core itself.

Unless I'm missing something, and if so, please let me know and I'll go
fix it up.

thanks,
