As title says Zoom buttons on Logitech DiNovo Edge are not triggering any events.

My system is Fedora 12 (fully updated), x86_64 version.

However evtest gives following output when these buttons are pressed:

./evtest /dev/input/event4

Input driver version is 1.0.0
Input device ID: bus 0x3 vendor 0x46d product 0xc714 version 0x111
Input device name: "Logitech Logitech BT Mini-Receiver"
