dmesg
Honestly, it is not libinputs fault but the kernels. The kernel simply ignores
the tackpad, which is listed in lsusb, but ignored at all other levels. I tried
to force the usbhid driver to bind to it using echo -n "1-6" >
/sys/bus/usb/drivers/usbhid/bind and other similar commands. I also managed to
find the modalias of the usb device and tried to make it bind in
etc/modprobe/local-aliases.conf :
alias usb:v06CBp0081d0164dcFFdsc10dpFFicFFisc00ip00in00 usbhid
I provided lsusb, dmesg, devices in the attachement. We can see that the kernel
totally ignores the device for strange reasons.
It is a bug common on all lenovo yoga 720 15", the 13" version doesn't have
this problem. This laptop is expected to sell a lot because it is de facto the
most powerfull convertible available on the market.
