You don't need to go back so far, version 1.06 works aswell!

No, I've been using the UX2 only with USB 2.0 ports from the start!

I have the same issue with Windows 8 Pro x64. I have tried every single solution mentioned it this thread, but nothing seems to work for me. When the sound drops I'm not even able to restart the PC from Windows - when I press Restart, Windows hangs on the Restarting and rotating circle screen! Only pressing the reset button on my PC helps. Line 6, you have to find a fix for this, because I think the UX 2 driver is causing these problems.. So, now I'm back to Windows 7 till they'll fix it!
