i2c-hid touchpad synopsys designware I've got the hold on a Fujitsu Ultrabook U7411/U7x11 which has some glitches/quirks with the touchpad that can be fixed with modprobe i2c-hid. ( Ubuntu 20.04 / 5.8.0-53-generic ) In dmesg I can see this when I modprobe it: i2c_hid i2c-0X53 0X59 0X4E 0X50 0X31 0X46 0X31 0X35 0X00:00: supply vdd not found, using dummy regulator After this it appears in xinput and works: 0X53 0X59 0X4E 0X50 06CB:CE2B Touchpad id=19 Any clues / suggestions to make this work "out of the box" are appreciated.
