I bought them at the Maker Faire in NY and I had no trouble setting them up. But about two weeks ago they both stopped working.

Here is the message:

Note the message: Pool 0 is hiding block contents from us

What is going on?

It's OK ... see: https://bitcointalk.org/index.php?topic=910629.0
But you should take care of the: "NO DEVICES FOUND: Press 'M' and '+' to add" message
