Interfacing Linux: Phonic Firefly 202

Sometimes you run across an interface that you never knew existed. While I was aware of the Phonic Firefly 808 and 302 the 202 caught me, off guard. It’s a curious little device from the days of firewire past.

At the end of the day you have a chonky bus-powered metal box limited by 1/4-inch jacks and no access to the internal mixer. Granted, the Firefly 202 works out of the box if you can live with those restrictions.

I would only suggest buying one if you were in the market for a novelty foot warmer.
