Same problem, build #1024. This output not just flood all tty, but also my dmesg (no output in "# dmesg" except the bellow):
wsmouse1 detached ums1 detached uhidev2 detached uhidev2 at uhub3 port 6 configuration 1 interface 0 "Logitech USB Optical Mouse" rev 2.00/63.00 addr 4 uhidev2: iclass 3/1 ums1 at uhidev2: 3 buttons, Z dir wsmouse1 at ums1 mux 0 Probably not a problem in USB 3.0, since I had the same issue on old builds in a hardware with USB 2.0. I'll follow this thread, because this is really annoying for me (I need to remove my mouse everytime I do something in tty).
