Comment 72 for bug 1504445

This bug also affects my Asus X455LF-WX055T with FocalTech Touchpad with Ubuntu 16.04 LTS installed.

I noticed a change in `xinput list` before and after suspending

Before I suspend, my `xinput list` contains `PS/2 FocalTech FocalTech Touchpad`:

xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech K270 id=10 [slave pointer (2)]
⎜ ↳ Logitech M315/M235 id=11 [slave pointer (2)]
⎜ ↳ PS/2 FocalTech FocalTech Touchpad id=15 [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)]
    ↳ Video Bus id=8 [slave keyboard (3)]
    ↳ Sleep Button id=9 [slave keyboard (3)]
    ↳ USB2.0 VGA UVC WebCam id=12 [slave keyboard (3)]
    ↳ Asus WMI hotkeys id=13 [slave keyboard (3)]
    ↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)]

When I wake it up after suspending it, my `xinput list` does not contain `PS/2 FocalTech FocalTech Touchpad` but it was replaced(?) by `AT Raw Set 2 keyboard id=15 [slave keyboard (3)]` which was not present before I suspend:

xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech K270 id=10 [slave pointer (2)]
⎜ ↳ Logitech M315/M235 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)]
    ↳ Video Bus id=8 [slave keyboard (3)]
    ↳ Sleep Button id=9 [slave keyboard (3)]
    ↳ USB2.0 VGA UVC WebCam id=12 [slave keyboard (3)]
    ↳ Asus WMI hotkeys id=13 [slave keyboard (4)]
    ↳ AT Translated Set 2 keyboard id=14 [slave keyboard (3)]
    ↳ AT Raw Set 2 keyboard id=15 [slave keyboard (3)]

I hope this helps...
