I've been following the developments of the new version of BFG Miner and they've released a beta build that supports the U1's and BE's. 

I'm on Windows but am using the modified BFG Miner with both U1's and BE's on the same hub just fine.  There are posts that you may find helpful there at: https://bitcointalk.org/index.php?topic=168174.1940

Hope this helps.
