Does anybody know the necessary kernel modules to get the T14s trackpad working? In lsusb, there is a device for synpatics inc (06cb:00f9), but it does not show up in libinput

juliedeville,

Share dmesg on a pastebin please. All of it. WE need to see what is missing as well as what is there.

juliedeville,

Here is your device being detected in dmesg.
Code:
[    2.601830] usb 3-3: new full-speed USB device number 2 using xhci_hcd
[    2.730763] usb 3-3: New USB device found, idVendor=06cb, idProduct=00f9, bcdDevice= 0.00

but there is no driver for it.

I was expecting to see it as a generic mouse.

Code:
Linux version 6.6.74-gentoo
looks like gentoo sources.

Does your kernel have
Code:
  ┌────────────────────────────────────────────── Synaptics USB device support ──────────────────────────────────────────────┐
  │ CONFIG_MOUSE_SYNAPTICS_USB:                                                                                              │ 
  │                                                                                                                          │ 
  │ Say Y here if you want to use a Synaptics USB touchpad or pointing                                                       │ 
  │ stick.                                                                                                                   │ 
  │                                                                                                                          │ 
  │ While these devices emulate an USB mouse by default and can be used                                                      │ 
  │ with standard usbhid driver, this driver, together with its X.Org                                                        │ 
  │ counterpart, allows you to fully utilize capabilities of the device.                                                     │ 
  │ More information can be found at:                                                                                        │ 
  │ <http://jan-steinhoff.de/linux/synaptics-usb.html>                                                                       │ 
  │                                                                                                                          │ 
  │ To compile this driver as a module, choose M here: the                                                                   │ 
  │ module will be called synaptics_usb.
