ASUS T102HA Camera and fingerprint not working

Hi all, thanks for Fedora 30 which worked out of the box on my device after I had tried many other distros!
The only bits not working are the face camera and the fingerprint sensor.
Here are the results from lsusb and lspci for anybody who can help:

lsusb

Maybe somebody can help with this. Many thanks in advance!

  1. For the FingerPrint Reader as you can see a message below that device , you need additional driver to support it, specifically libfprint :
dnf provides libfprint
sudo dnf install fprintd-pam fprintd libfprint

You can use command line:

fprintd- # and press TAB

the list are the follow:

  • fprintd-delete
  • fprintd-enroll give you (I read somewhere that libfrprint doesn’t support ELAN device) and here is your devices… and how to compile…
    • list_devices failed: No devices available, you will need to compile by yourself
  • fprintd-list
  • fprintd-verify

https://help.gnome.org/users/gnome-help/stable/session-fingerprint.html.en or in your gnome -> session configuration -> devices…

  1. For the camera, I don’t see any in your PCI configuration:

Could you please provide:

lsusb -t

I would like to know what program do you use to test your camera? you can try to install cheese

Regards.,

Hi,
thanks for ‘rapid’ response!

  1. Here is the lsusb
    lsusb -t
    /: Bus 02.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/6p, 5000M
    /: Bus 01.Port 1: Dev 1, Class=root_hub, Driver=xhci_hcd/7p, 480M
    |__ Port 2: Dev 2, If 2, Class=Human Interface Device, Driver=usbhid, 12M
    |__ Port 2: Dev 2, If 0, Class=Human Interface Device, Driver=, 12M
    |__ Port 2: Dev 2, If 1, Class=Human Interface Device, Driver=usbhid, 12M
    |__ Port 3: Dev 3, If 0, Class=Wireless, Driver=btusb, 12M
    |__ Port 3: Dev 3, If 1, Class=Wireless, Driver=btusb, 12M
    |__ Port 4: Dev 4, If 0, Class=Hub, Driver=hub/4p, 480M
    |__ Port 2: Dev 5, If 0, Class=Vendor Specific Class, Driver=, 12M

You can also look at my hardware profile which lists a device similar to a camera.
2. I have tested with cheese and there is no device found on that.
3. Compiling the ELAN driver is almost impossible because it always returns an error saying that glib-2.0:
“meson.build:42:0: ERROR: Dependency “glib-2.0” not found, tried pkgconfig and cmake”
in spite that it is installed but probably not in the right folder the meson searches for it! I am almost giving up on that one!

Thanks again!

About the fingerprint, this is the comparative Table between Distros:

| DEBIAN          | FEDORA        |
| -----------     |:-------------:|
| libglib2.0-dev  | glib2-devel   |
| libnss3-dev     | nss-devel     |
| libpixman-1-dev | pixman-devel  |
| libusb-1.0.0-dev| libusb-devel  |
| libx11-dev      | libX11-devel  |
| libxv-dev       | libXv-devel   |
| pkg-config      | pkg-config    |
| -----------     |:-------------:|

Hi hhlp,
thanks for that info.
I have done everything as per the compiling instructions but still get the error about glib2.
I have installed glib2-devel and the same error again ocurred. So,I have given up the compiling excersise! I’ll wait until fedora puts it into the kernel.
The camera is a mystery since it has never worked according to linux-hardware.org
Thanks again for your help!

Anything else???
Am I alone on the fedora planet???:wink::crazy_face:
