Eleven Rack Keeps Disconnecting

[CliffT]

Just Got the Eleven Rack and I am floored by how awesome it is. It's exactly what I've been looking for and it sounds frickin' awesome. Makes we want to play guitar all day again.

But...

The damn thing keeps disconnecting.

If I'm in Pro Tools I can work for about 1/2 and hour before I get the message:

"Pro Tools cannot communicate with Eleven rack."

Once that happens I have to shut down the whole system and restart.

If I'm in Ableton Live or Reason or just listening to music in iTunes the same thing happens, just without an error message. In those cases I just power down the 11R, restart it and it's working again.

I've updated the firmware. I've disconnected all external USB stuff (hard drives, MIDI controller, printer). I've tried different USB ports.

Update: This seems to happen every time I step away from Pro Tools, leaving the system idle for a few minutes. In other DAWs it seems to happen randomly.
