Yeah... I had installed drivers from Line 6 Monkey and Pod Farm installed as well.
I would open pod farm and everything was working fine on the Pod Farm, software and needle moved just like your explaining and Windows showed interface hooked up on recording tab but no green bars appeared as if the interface was some how just half way detected...
When I deleted UX2 from devices and printers and unplugged/plugged back in USB, my interface did a little mini install thing through windows and the interface was detected all the way and I was able to see the green bars on my device and started to get the thing working for individual programs like Audacity...
Before I did any of this though... I did try to unplug interface and swap USB ports with it while computer was on and I was able to get it working that way too... Try swapping USB ports if you haven't and see if it starts to work. c:
