eCosCentric have a closed source, pay money, solution using the Jungo
stack.

Im not sure that would be the right solution for an embedded system. I
think it will be too general, assume a filesystem where USB device
drivers live as loadable kernel modules etc. For a deaply embedded
system this does not make too much sense. You will decide at compile
time which USB devices you are going to support and compile them into
the application.

There has been some talk of a native, open source host support, but
nobody actually did any implementation work :-(
