I'm trying Logitech K400 (wifi keyboards plus touchpad) and so far so good seems working well except:
This crazy behavior:
1) If I double tap a directory it wont open, while, if I do the same with the button (right) it will without problems.
If I double tap it with the touchpad of the laptop it will open as well.
2) If I touch the touchpad of the laptop it will "middle click" without issues.
While if I do so with Logitech's touchpad it will do nothing.. Instead if I two-finger click the buttons of the touchpad it will middle click.
Some configuration:
synclient -l

I think something is overlapping somewhere but I'm to tired to think straight at the moment.

Any idea?

I use the K400+ too. The touchpad is identified as a pointer (not like a touchpad). The options may be set with "Identifier Pointer".
Look at your listing:
$ xinput list
⎡ Virtual core pointer id=2 [master pointer (3)]
⎜ ↳ Virtual core XTEST pointer id=4 [slave pointer (2)]
⎜ ↳ Logitech K400 Plus id=11 [slave pointer (2)]

Whats your xinput list?

This is as weird as it can get.
I tried also to force the configuration:
xorg.conf.d]$ cat 00-pointer.conf
Section "InputClass"
Identifier "libinput pointer catchall"
MatchIsPointer "on"
MatchDevicePath "/dev/input/event*"
Driver "libinput"
Option "HorizontalScrolling" "0"
Option "AccelProfile" "adaptive"
Option "DisableWhileTyping" "1"
Option "MiddleEmulation" "0"
Option "NaturalScrolling" "false"
Option "ScrollButton" "0"
Option "Tapping" "on"
Option "TappingButtonMap" "lmr"
EndSection
Yet when I test the device (id 11 in my case) xinput test 11
Although the action is the same :
Below is an example when I use the touchpad double click different time and also double clicking with the button. Only the latest works. (meaning, trying to open a folder works only with the button and not with the touchpad although the action detected is exactly the same and my motion exactly the same).
button press 1
button release 1
button press 1
button release 1
button press 1
button release 1
button press 1
button release 1
button press 1
button release 1
button press 1
button release 1
button press 1
button release 1
button press 1
button release 1
button press 1
button release 1
button press 1
button release 1
button press 1
button release 1
button press 1
button release 1
I'm almost thinking this may be a firmware problem. I actually updated to the latest firmware, don't remember if the problem was before as well as after.

I have the same issue - started happening in the last 6 months or so. It seems that if your clicks are too close together, only the first is registered. If you do a slower double-click it works. I can't handle double-clicking that slow though.

I've looked into this and I strongly suspect it's due to the libinput devs messing about with debouncing and getting their timings wrong (probably introduced by v1.9 of libinput). Looks like there may be some changes coming in the next version of libinput that may resolve the matter but it's not clear exactly what issues are being fixed (https://www.phoronix.com/scan.php?page= … t-1.10-RC1).
In the meantime I've downgraded the libinput package to v1.8.3 and all seems to be back to normal

HI, I may have not understand, but that model has a combination to activate-deactivate the tapping feature (I'm not sure if it's Fn+Esc), also I think it doesn't have the middle button emulation.
Edith: sorry, as I had to realize, I was not understanding.
