I believe I'm encountering the same bug. I originally logged bug #993655 for this issue, I thought it was a Unity issue.
All my details are under the original bug, but to recap; I'm using 12.04 all up to date. My device is a wireless Plantronics headset, that uses a USB transmitter/receiver, the device model is D100. >From here, what can I do to help? -- You received this bug notification because you are a member of Ubuntu-X, which is subscribed to xorg-server in Ubuntu. https://bugs.launchpad.net/bugs/1007575 Title: SB Arena USB headset causes X BUG, can't click outside window To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/xorg-server/+bug/1007575/+subscriptions _______________________________________________ Mailing list: https://launchpad.net/~ubuntu-x-swat Post to : ubuntu-x-swat@lists.launchpad.net Unsubscribe : https://launchpad.net/~ubuntu-x-swat More help : https://help.launchpad.net/ListHelp
