I'm going to leave this as incomplete as I cannot find a kernel version where this doesn't show up. There's only one computer that I have that doesn't experience this issue and it is on 15.04.
At this point I'm suspecting some system service fiddling with the usb system? Consider how regular the intervals are. Is there a list of the services somewhere that I can look at and then check individually? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1521245 Title: Kinect Device keeps on disconnecting and reconnecting every two seconds Status in linux package in Ubuntu: Incomplete Bug description: I have an original xbox 360 kinect and when I try to use it with wily, it seems to keeps connecting and reconnecting.
