Touchpad is not detected

My touchpad doesn’t get detected. I can use my touchpad as a simple mouse, but without any extra features like scrolling. My notebook is a **Toshiba Tecra Z40-A-11R**. I'm running Elementary OS Freya (based on Ubuntu 14.04). My kernel version is **3.16.0-41-generic**. ## xinput list ⎡ Virtual core pointer id=2 [master pointer (3)] ⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)] ⎜ ↳ PS/2 Generic Mouse id=11 [slave pointer (2)] ⎣ Virtual core keyboard id=3 [master keyboard (2)] ↳ Virtual core XTEST keyboard id=5 [slave keyboard (3)] ↳ Power Button id=6 [slave keyboard (3)] ↳ Video Bus id=7 [slave keyboard (3)] ↳ Power Button id=8 [slave keyboard (3)] ↳ TOSHIBA Web Camera - FHD id=9 [slave keyboard (3)] ↳ AT Translated Set 2 keyboard id=10 [slave keyboard (3)] ↳ Toshiba input device id=12 [slave keyboard (3)] ## lsusb Bus 001 Device 002: ID 8087:8000 Intel Corp.
