Input from Sequential Stick Shift of "DFGT" not detected by linux device driver

I am trying to develop an application which runs on my new Raspberry Pi2. It gets its input from Logitech Driving Force GT (DFGT). I connected DFGT to RPi2 running on Raspbian. The device was recognized since DFGT is supported natively by the kernel. I used "jstest" program to test the device but the Sequential Stick Shift, + / - Rocker, Illuminated Horn and few other buttons are not working.

I used "evtest" and "evemu" to display the information about the input device including all the events supported by it. The buttons are not listed in the supported events.

To cross verify I ran "jstest" on DFGT through the software LTWheelConf and I was not disappointed. All the buttons were working.

Does it mean the problem is with the driver supported by the kernel? Is is possible that the events are being generated but I am failing to read them somehow? I am a newbie so I appreciate any help.

Thank you.

I can only offer basic advice as my experience with this is limited. Anyway, IMO it is likely down to the driver concerned. If you examine /proc/bus/input/devices
cat /proc/bus/input/devices
that should help you to determine the driver and the sysfs device in question.

It is also possible to read a raw input device (eg event3) like this
cat /dev/input/event3
just to check if there is a response to the buttons at all.
