I recently purchased this laptop and installed Ubuntu 18.10 alongside Windows 10. It has a fingerprint sensor integrated with the touchpad. While it works fine with the Windows, it is not even recognized by the Ubuntu.

Here's the output for the lsusb:

Bus 002 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub

Bus 001 Device 004: ID 8087:0a2b Intel Corp. 

Bus 001 Device 003: ID 13d3:56c1 IMC Networks 

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub

And here's the output for lspci:

This is because the fingerprint sensor on the Asus notebooks is not yet supported in the libfprint library. (It's the Elan Microelectronics reader)

See https://bugs.launchpad.net/ubuntu/+source/libfprint/+bug/1641290 and please add your vote by clicking the "yes, it affects me too" indicator at the top of the bug report. The more people show that they are affected, the greater the chance that this gets assigned to somebody to fix.

Because the hardware is not known, it doesn't even show in the lshw listing.
