I bought a Logitech K400 with wireless keyboard with touchpad integrated.
The problem is that the system doesn´t recognize the middle button (button 2) done pressing with 2 fingers in the touch.
The touch is working fine. Multitouch scrolling is working.
Here is my xinput
If I run "xinput test 9" the system catch all the events a part the double touch or the triple touch.
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech Unifying Device. Wireless PID:400e id=9 [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)]
Even xev down not catch these events.
Any idea how to enable the events?
