[arch-general] xfce-powermanager issue since kernel 3.19

Hi all, since having updated to kernel 3.19 xfce Power Manager Panel Plugin does not show my logitech trackball (m570) and keyboard (k230) both connected through wireless usb dongle. other logitech device (logitech m235 mouse) does. all are shown with lsusb: $ lsusb | grep Logitech Bus 004 Device 005: ID 046d:c52b Logitech, Inc. Unifying Receiver Bus 004 Device 004: ID 046d:c52f Logitech, Inc. Unifying Receiver Bus 003 Device 007: ID 046d:c52b Logitech, Inc. Unifying Receiver and all work fine. downgrading to kernel 3.18 solves this issue. This is nothing making me sad all the day :o)) Nevertheless I'm a little bit lost where to report what? -- Friedrich
