I'm not sure it is a X driver bug, but found the following in the log:

[    18.552] (**) evdev: Plantronics Plantronics C620: Device:
"/dev/input/event0"
[    18.552] (--) evdev: Plantronics Plantronics C620: Vendor 0x47f
Product 0xaa00
[    18.552] (--) evdev: Plantronics Plantronics C620: Found 18 mouse buttons
...
[    18.552] (II) evdev: Plantronics Plantronics C620: Configuring as mouse
[    18.552] (II) evdev: Plantronics Plantronics C620: Configuring as keyboard

And ignore identifier "Plantronics" fix the problem for me:

Section "InputClass"
        Identifier      "Plantronics"
        MatchProduct    "Plantronics"
        Option          "Ignore" "true"
EndSection
