    Hmm. I can't test it myself because (A) I don't have a board with a
    working input FIFO and (B) returning the bus to ECP forward mode will
    (I've since learned) cause other strangenesses in the ECP hardware I
    have to test with. (In particular, returning it to forward mode will
    cause a new header to be sent the next time it reverses, which could
    lead to unexpected input from the read call.)

    If I get a board with a working input FIFO (hopefully in the next few
    days) I can try this patch and find out for certain what happens to my
    data stream...
