However after restarting the > machine, the pointer device was just connected and working. It seems the problem is LL Privacy (aka. Address Resolution), when that is enabled certain controller seem to be unable to resolve addresses so the ho= st stack is unable to reconnect. I guess we should be splitting the kernel experimental features from userspace experimental features, anyway Experime= ntal is never meant to be enabled by default so if anyone is shipping with it enabled on main.conf please reconsider. --=20 You may reply to this email to add a comment.
