libusbg-neXt (libusbgx)
-------

libusbgx is a C library encapsulating the kernel USB gadget-configfs
userspace API functionality.

It provides routines for creating and parsing USB gadget devices using
the configfs API. Currently, all USB gadget configfs functions that can
be enabled in kernel release 3.11 (Linux for Workgroups!) are supported.

See the Doxygen docs and examples for complete details on the
programming API and INSTALL for installation of the library and
examples.

To run the examples:

$ modprobe configfs
$ mount -t configfs none /sys/kernel/config
$ gadget-acm-ecm
