How can I disable and turn off the fingerprint reader embedded in my Dell XPS 13 (7390)?

The device is a HTMIcroelectronics Goodix Fingerprint Device, USB ID 27c6:5385.

Powertop warns that it is constantly on (although I never use it) and it is unnecessarily draining the battery of the laptop.

If you never use it, see if the laptop's BIOS settings allow you to fully disable it.

It seems that your case is almost the same as in mine XPS 15.

Create file /etc/udev/rules.d/fingerprint.rules and place there following text:

# Disable fingerprint reader
SUBSYSTEM=="usb", ATTRS{idVendor}=="27c6", ATTRS{idProduct}=="5385", ATTR{authorized}="0"

This disables usage of usb device with vendor and product ids defined above. Changes should be used by udev after reboot.
