Hi all! I have been lurking here a while, trying to absorb some of your invaluable experience and knowledge about this gloriously fun stick miner. For now I am running 2 of them in a powered hub / Raspberry Pi setup, and I have managed to tweak them both to run solidly at 225MHz with no HW errors in sight. Lovely.

One aspect that I haven't been able to find much information about though is the difficulty setting. How does this come into play, and what difference does it make if I set it to for example 32, 64, 128 or... Something else.

Looking through the thread, and peering at the various screenshots of cgminer running I can tell that different people on here run at different difficulty settings. I also vaguely recall from when I set up the first stick I received that I saw a recommendation on setting --suggest-diff to 32, so I used that for a long time. But having played with it the last couple of days I can't really see anything happening if I change it?

Any insights on this would be much appreciated, or links to a place where this may already have been explained (my sincerest apologies if I missed it previously in the thread).

Thanks for all your contributions on here, this thread is gold!
