-------

libusbg 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:

$ mount -t configfs none /sys/kernel/config

$ gadget-acm-ecm

$ show-gadgets
