ZOTAC AD12 / ASL with 2 nodes?

I’ve got my 2 node setup running fine on an AOpen DE7000, but I’d like to use a fanless mini PC. I’m trying a ZOTAC AD12, which uses an AMD E2-1800, dual core, 1.7Ghz processor. It runs a single node just fine. When I try to run 2 nodes, the system stops talking to the URI’s ( 1 DMK, 1 RA42 ). Both URI’s do show up with ’ lsusb '. Any thoughts? Not sure how to debug this. The DE7000’s will be reliable for a remote site, but fanless would be better.

DUH. My error! I did not update usbradio.conf for 2 nodes. Sorry for the confusion.
