Comment 28 for bug 993655

I'd spent the weekend dealing with this as last week someone at work gave me one of these plantronics devices to use, and I was stoked it would act as a headset for my pc as well. Then I started getting the screen freeze issue, and never figured out it was linked to the stupid headset. After upgrading from 12.04 to 13.10 (hitting a ton of ubuntu bugs along with the way with the intel 4000 video chipset, forcing me to hit 13.10 until I got a stable system again), and trying every window manager out there, still had this issue... Seemingly after doing anything that triggered the sound device, finally figured out it was related when disconnecting the plantronics headset would allow me to click on my display windows again. Argh!

If nothing else, can you (Canonical) simply blacklist the device by default, or at least add the xorg entry if you can't find a better way of dealing with it? This is likely to make any user lose their hair as it about did for me.
