Thunderbolt ethernet disconnected when USB assessory connected

I've been using an thunderbolt ethernet adapter for a couple of weeks with no problems. Now I'm trying to connect a USB conference phone for skype calls. When I connect the conference phone to my usb port, the ethernet disconnects from the thunderbolt port.


Is there a way to connect a USB item and the thunderbolt-ethernet adapter at the same time?


Thanks!

MacBook Air (13-INCH, MID 2011), Mac OS X (10.7.4)

It is definitely possible to use USB ports while having ThunderBolt to Eth in.

The problem you may be having is the conference phone which would probably appear as a communication devices in your Networks.

What you can try is: connect both cables TB and USB
in System Preferences > Networks

Set Service Order (cog icon bottom of the window)

This changes the preferable connection device.


See if that helps - otherwise this is some kind of conflict with third party conference phone.

Post back your results.
