I think CityK confirmed that the nxt2004 driver statistics are probably bogus so I doubt you're going to get your 115's running with BER 0 regardless, which is unfortunate. Assuming your original configuration was fine, the second part of the problem remains then.... is the DMA being screwed by the mix of boards. I'm not sure I have an easy way for you to determine this, other than making sure everything is on it's own interrupt, going back to basics to a single 115 and a single 250 and trying to isolate the changes step by step. - Steve
