With the move to configfs for creation of arbitrary USB composite gadgets, I found myself wanting a simple C library to configure and parse gadgets in a system. It has no other dependencies other than libc itself. It can be found at: git://git.linaro.org/people/mporter/libgadget.git Doxygen docs on API and examples at: http://people.linaro.org/~matt.porter/libgadget/group__libgadget.html http://people.linaro.org/~matt.porter/libgadget/examples.html Output from the examples: $ mkdir /config $ mount -t configfs none /config $ gadget-acm-ecm $ show-gadgets ID 1d6b:0104 'g1' UDC 3f120000.usbotg bDeviceClass 0x00 bDeviceSubClass 0x00 bDeviceProtocol 0x00 bMaxPacketSize0 0x40 bcdDevice 0x0311 bcdUSB 0x0000 idVendor 0x1d6b idProduct 0x0104 Serial Number 0123456789 Manufacturer Foo Inc.
