Hardware: HP ZBook 15 G2, Logitech M-UAS 144 After the big drawback beginning from kernel 3.19, when nouveau began to be broken for the above hardware (until now), there is another one, introduced with kernel 4.4.0 in Tumbleweed: After boot/reboot, the connected USB mouse does not initially work in both cases, connected to the docking station and connected directly to the notebook. After disconnecting and reconnecting it physically the mouse works immediately. Sometimes I have been noticing the same behavior for the USB keyboard, but not everytime. I hadn't have this behavior before 4.4.0. Still not solved for 4.4.1. I cannot guarantee that this happens along with another update that came beside to kernel 4.4.0, usually I do a 'zypper dup'. Using sddm as display manager. In /var/log/messages I haven't found anything suspect, the USB devices are initialized and the mouse is actually recognized but does not work after this one: 2016-02-24T14:01:22.775406+01:00 rkrell kernel: [ 5.821627] usb 3-2: New USB device found, idVendor=046d, idProduct=c062 2016-02-24T14:01:22.775408+01:00 rkrell kernel: [ 5.821642] usb 3-2: New USB device strings: Mfr=1, Product=2, SerialNumber=0 2016-02-24T14:01:22.775408+01:00 rkrell kernel: [ 5.821643] usb 3-2: Product: USB Laser Mouse 2016-02-24T14:01:22.775408+01:00 rkrell kernel: [ 5.821645] usb 3-2: Manufacturer: Logitech 2016-02-24T14:01:22.775409+01:00 rkrell kernel: [ 5.821850] usb 3-2: ep 0x81 - rounding interval to 64 microframes, ep desc says 80 microframes The USB keyboard works already in this state.

Any further victim of this bug, hint, is this a known problem or is there a workaround?
