I have the same interface and had the same problem. You'll have to use the old Alesis driver package. (3 Alesis1394Audio_1.5d0.pkg) They are having issues with the latest mac driver update (3 Alesis1394Audio_1.5d4.pkg) Go to the Alesis support page for the i/o and download their update package. Here -->Run the Alesis Clean app, then reinstall the old driver (3 Alesis1394Audio_1.5d0.pkg). It should work fine after making the appropriate settings on your mac System, and Audio Midi setup, and your DAW software.

Usb Network Server 652 Manual here. 4.10 I can get levels on the IO/26 if the unit is pluged in with its own power unconnected to the mac or with the firewire interconnect, until the computer fully boots. Then I get no levels on the IO/26. The yellow fire wire and green sample rate lights stay on. Any levels on the unit when it was plugged into my lap top. It was determined I had a defective unit. However, the replacement is doing the same thing. So, I suspect there is something the fellow from support missed.
