Does anyone know of an example project with a USB device implemented with

I have built rtems-libbsd for the realview_pbx_a9_qemu and for the
altcycv_devkit. The USB examples in the testsuite all appear to be USB
host-mode tests. What I want to do is to create a system that will present
a USB composite device that I can connect to a USB host. The composite
device is to have a USB bulk IN endpoint, a USB bulk OUT endpoint and a USB
HID IN endpoint. I'm trying to find out whether I can do this on RTEMS. I
have all the relevant USB descriptors from my implementation that uses USB
gadgets on Linux. I want to port the application to an RTOS.
