Lsusb command not detecting my fingerprint sensor

Hey everyone, I am a new linux user and I have just installed Fedora 34 on my asus vivobook x509jp laptop. But when type in the command lsusb in the terminal it did not detected any fingerptint sensor. I tried to install fingerprint gui but it is also not installing.
Please help.

Are you sure that the fingerprint sensor is not listed at all or is it possible that you have unknown devices (i.e. without or with weird names) that are hiding the fingerprint sensor?

Can you please look through the kernel log (e.g. with journalctl -k) and have a look whether there are any errors reported related to usb? If you are unsure, can you please paste the output of journalctl -k | grep usb? (If the output is very long, please use a pastebin service such as https://paste.centos.org/)

Is it possible that the fingerprint sensor is disabled in BIOS?

Are you using usbguard directly or indirectly (what does systemctl status usbguard.service say?)? Or are you using udev rules to ignore some devices? Or do you have you set something like usbcore.authorized_default=0 to the kernel cmdline? What does less /sys/bus/usb/devices/usbX/authorized_default say for the different USB root devices? (See also here, and here)

Fingerprint sensor setting is not mentioned distinctly in BIOS.

Unit usbguard.service could not be found.
/sys/bus/usb/devices/usbX/authorized_default: No such file or directory

Sorry, I forgot to mention to replace the X with numbers for each of the files usb0, usb1, … in /sys/bus/usb/devices/.

How about ls /dev/spi*?

If it is not connected through SPI (see @ozeszty’s comment), what’s the output of lsusb and lsusb -t?

According to /usr/share/hwdata/usb.ids,

  • usb 1-10 is an intel bluetooth adapter
  • usb 1-4 is a card reader
  • usb 1-5 is the webcam

So it looks like the device is missing here.
