I2C-HID Quirk 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:

After this it appears in xinput and works:

CONFIG_SND_DESIGNWARE_I2S=m
CONFIG_SND_DESIGNWARE_PCM=y
CONFIG_I2C_HID=m

I already found that this is the Microsoft HID over I2C protocol and that this has some issues because of the implementation.

Any clues / suggestions to make this work "out of the box" are appreciated.
