    Ah, I didn't realize that you want it to be used by some acutal userspace
    applications. Out of curiosity -- what is the usage pattern you are
    targetting?

    The idea behind debugfs-provided userspace descriptor is that driver
    developer is easily able to inspect the descriptor, and write a kernel
    driver that fixes it up in case it is bogus.
    There were also efforts to make the report descriptor replaceable in a
    request_firmware() way, but that never converged to state in which it
    could be applied IIRC.

    Thanks,
