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:

This works. I have both a Jalapeno and a U1 running for a total of around 8gh/s. All mine is done in terminal and using one instance of bfgminer. Trying now to set it up to allow some of the hashes to go towards solo "lotto" minning (around 10%). No luck on doing that yet!
