Hello,
I have the headset for a few days only, and yet I'm affected by the auto-shutdown bug. I was discussing on Skype and it occurred like 8 times in an hour. Everytime this happens, I have to fire up the CUE program and click on the "Surround" button for example to cancel the auto-shutdown...
The USB receiver is plugged on an USB 3 port on my motherboard, and my configuration is in my profile.
Hope you fix it soon. That's really annoying as that makes the headset nearly unusable!
