Exactly the same device, but now cfg #1 is active and a 
different set of
drivers have bound to the interfaces.  This is possible 
because none of
the involved drivers disable the support for this device at 
build-time.
Instead they use the available interface descriptors for matching and
probing supported functions.

End users will of course normally not go around writing stuff to sysfs
attributes like this.  Creating an udev rule to select a specific
counfiguration when the device is plugged is more useful for normal
usage.

Thanks for your answer. I would study udev rule first.
Does the udev alwayes exist for all Linux system, such as
Android, embedded system, and so on?
