Thank you for your really prompt reply, and apologies if this is simple stuff.
MultiMiner is running the following command in order to detect your devices. Can you run this command and let me know what is returned?
bfgminer -S all -d?
Here's what's returned:
bfgminer -S all -d?

You an also try disabling GPU and enabling the Erupter specific driver. Both of these are in Settings and then Advanced miner settings.
I've done those settings, but to no effect.
This is the equivalent of:
bfgminer -S erupter:all -G -d?
Running the above in the terminal, I get one less iteration of no user privileges, and nothing about OpenCL:
bfgminer -S erupter:all -G -d?

If the above commands are showing your Erupters then technically MultiMiner should as well.
USBs 0-2 are the Erupters. Do I need to run MultiMiner as sudo somehow, as I do bfgminer? I've never used Mono before.
