Hi,
I've upgraded my Distro Ubuntu from 14.04 (Kernel 3.13.0) to 16.04
(Kernel 4.4.0).
Since the upgrade the battery indicator LEDs on my Logitech Performance MX Mouse
light up about every 60 seconds. Depending on the charging level 1, 2
or 3 LEDs light up green.
I've used the usbmon module to capture the usb traffic and when the
LEDs light up the following
is captured by "cat /sys/kernel/debug/usb/usbmon/2u":

If you have any idea how to disable or fix that behavior please let me know.
If you need further information to debug this properly please also let me know.
Thanks for your efforts!
Best regards,
