DC-1 USB and extrnal device lockups

[samyount]

Here's the situation:
I have a brand new Macbook pro running 10.10.3 (Latest as of posting).  When I have the Mac on and then connect the Emotiva, it locks up my other USB/Bluetooth devices.  The external keyboard (BT) and the Mouse (Wireless USB) both stop responding to any inputs.  The only fix seems to be rebooting the computer.  If the DC-1 is on and plugged in when I boot the machine, no issues.  It's a really annoying problem as I frequently have the laptop on when I sit back down at my desk and plug in the DC-1.   For reference, I also have a TEAC UD-301 and it doesn't have any of these issues.

Anyone else experienced this?  Any fixes?

Different USB cable, different USB out from the Mac doing the same?

Your Mac has fallen asleep!         

My my wireless keyboard has a wake button on it, and then it's just fine!!

It's definitely not that the computer has fallen asleep. I can be actively using it, turn on the Emotiva and mid keystroke or mouse movement, the devices freeze. I will try a different cable and see if that makes a difference.
