How can I find my sensor id if it's not showing up on lsusb?

xk flag

I dualbooted my windows 11 with Ubuntu 22.04 LTS. But I've been unable to use my laptop's built-in fingerprint sensor.

The allow fingerprint authentication setting is just not present.

I searched a bit and found that not allow sensors are supported and got the list of supported sensors, which is here.

I ran lsusb to see the name of my fingerprint sensor and check if it's available or not, but the name wasn't present in the list.

Now some details for you guys:

  1. Does the sensor even work? : Yes I use it easily in my windows partition.
  2. Name of my laptop : Asus Vivobook 15 X1502ZA
  3. Name of my sensor found in the windows device manager: Elan WBF fingerprint sensor
  4. I then checked the properties in the device manager and got these hardware ids :
ACPI\VEN_ELAN&DEV_7001
ACPI\ELAN7001
*ELAN7001
  1. This is what lsusb returns: Yes, just five lines.
Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub
Bus 001 Device 003: ID 3277:0029 Shine-optics USB2.0 HD UVC WebCam
Bus 001 Device 002: ID 1c4f:0002 SiGma Micro Keyboard TRACER Gamma Ivory
Bus 001 Device 004: ID 13d3:3563 IMC Networks Wireless_Device
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
  1. Someone mentioned somewhere that the sensor might be turned off in the BIOS: Not the case for me as I use it in my windows partition.

I can't even check if my sensor is supported as the xxxx:xxxx ID is just not available to me. I see the name Elan in the list of supported sensors but there are lots of Elan sensors. To see if mine is supported, I want that ID. Can they be found by the hardware ids I found in the windows device manager.

Tell me if anything else is needed.

Thank You

Check the other busses, might not be on the USB bus. The sd bus may be used, look in /sys/bus/sdio

@ubfan1, Both the folders, Devices and Drivers, inside the sdio are empty.

OK not on the sdio bus. lspci for the pci bus, and if nothing obvious, maybe wade through the dmidecode output to see the device details.

Watch your system start up and detect its hardware with the terminal command `sudo journalctl -b 0`.

Most people don’t grasp that asking a lot of questions unlocks learning and improves interpersonal bonding. In Alison’s studies, for example, though people could accurately recall how many questions had been asked in their conversations, they didn’t intuit the link between questions and liking. Across four studies, in which participants were engaged in conversations themselves or read transcripts of others’ conversations, people tended not to realize that question asking would influence—or had influenced—the level of amity between the conversationalists.
