Just found the missing drivers that address that issue.Intel® Serial IO Driver for 11th Generation Intel® NUCs Ref: Solved: Latitude 5420 I2C HID Driver bang in Device Manager - Dell Community Cheers.
I have a Dell Latitude 5420 on Win 10 and none of the touchpad gestures work. The only thing that works on the touchpad is clicking and moving the cursor. Two finger scrolling doesn't work etc. When I click on the touchpad in settings there are no options even available. It appears to be missing a driver and when I try to install one it says there are none available because they are automatically installed with Win 10?
