You can verify by adding the VID/PID of your device to struct 
hid_device_id lg_devices[] with LG_RDESC flag.

I did, but without success (I didn't see the line "fixing up Logitech 
keyboard report descriptor" in the kernel logs). In user-space, the 
device needs to be poked to get the device to do something when the 
extra keys are pressed. I guess something similar is needed here.

Please compile the kernel with CONFIG_HID_DEBUG, modprobe the hid module 
with 'debug=2' and send me the report descriptor of the device (that 
appears in the dmesg output when the device is connected) as well as the 
output that appears when you press the non-working keys.
