The Zen mini mk 2 only has USB out. I also assumed it would work when I bought a used Codex. But I am having problems. I thought I had found the solution when I reset the latency of the Innuos to normal instead of low, but still have USB communication loss before I can finish one movement of a classical work.I am now using a very basic USB cable in place of the Straight Wire USB-Link, and it has lasted 90'.
I stlll would like to hear from any users with actual experience.
