Re: [avrdude-dev] patch #5655, again

[Jason von Nieda]

One thing I have noticed with the Crosspack version is that the first time I
use it after powering the mkII up it works fine. Subsequent runs against the
mkII without a power cycle work but there is anywhere from a 5-30 second
delay before the initialize happens. I believe I've posted to this list
about it. I found that the patch that skips the sign-on fixes that as well.
