First you need a gadget udc software that handles your USB hardware. Look in .../drivers/usb/gadget. If you don't see your device supported, maybe you should change devices? It is pretty difficult to debug and write a udc. Then you need gadget software that actually runs the device. For something slow like HID you should probably learn about gadgetfs. I don't see any current gadget for HID in the kernel source, so you will have to write your own. If you have a known good udc, gadgetfs is much easier to debug. It is not as easy to use as host side usbdevfs, but still, there is a sample for a gadgetfs driver.
