I had communication problems with Innuos Zen and Zenmini with my Ayre Codex DAC, including this one. Resolved by using a USB hub to help with I guess galvanic isolation.
Just send a note to Innuos support and they will get back to you.Also you may wish to update to firmware 2.0 to see it that helps, it is available now for Zeniths.
