Thanks much.
Hmm, that is odd, have you tried swapping out the USB cable yet? Sometimes it's the last thing you expect. It sounds to me like driver issues, or a bad cable! Assuming you've exhausted the all the right details on Firmware Updating requirements, and matching to the right M2 version for your OS, I would recommend reaching out to Apogee Tech Support, they are Ninja's of Stealth Wizardry, and will be able to trace the root of your issues.
The PCie card has a lower DSP profile, which means it will boat right along, at low buffer's, and will not eat up resource, while you add a greater work load to the Computer. This card allows for higher channel count's, and lower throughput latency. It is the premier interfacing method with Symphony I/O, and really the best way to attach the unit to a Mac Pro, in my experience. However, USB Mode is a really great achievement as well, and I have not had any issues with it, on my Mac Pro 8-core Dual Quad 2.66 machine, running on 10.6.8.
It has been surprisingly good!!
I am sure Apogee will be able to help work through your issues.
