I'm pretty sure you can use ethos to mine ubiq. Just change your pools to Ubiq pools. Not sure about solo mining but it shouldn't be very complicated.
I initially used the ethminer that comes as part of the nicehash miner, just pointed the miner to a ubiq pool.
I'm looking for the answer to this too.
Tried configuring ethos to mine a Ubiq pool and it worked for about 8 hours and then stopped working, connection to pool error. Tried on another pool and got the same error.
Switched back to mining Ethereum until I can find out how to correctly connect to a Ubiq pool.
Should be easy to setup , just take a look at your config file (here the example with everything explained)
