hi all:
I read this article, but I can't understand this section：
############################################################
Most USB device drivers should pass these tables to the USB subsystem as
well as to the module management subsystem. Not all, though: *some driver
frameworks connect using interfaces layered over USB, and so they won't
need such a "struct usb_driver".*
############################################################
From: https://www.kernel.org/doc/Documentation/usb/hotplug.txt
How to understand "using interfaces layered over USB"?
Thank you.
