    Unfortunately I don't know how the chips works wither. This method comes
    from the drivers I used as a reference. I have recoded the loop a little so
    it doesn't DELAY and I've never had a timeout from it.

    Me neither, but my laptop needs some help in that area, so that's what I'm
    going to look at next.
