            Bug ID: 266819
           Summary: ID 06cb:75bf not recognized as Synaptics
           Product: Base System
           Version: 13.1-STABLE
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Some People

I'm attempting to get the touchpad working
on my fresh FreeBSD 13.1 install
FreeBSD 13.1-STABLE n252407-f42139db639: Fri Sep 16 02:35:00 UTC 2022.
An attempt from a 14 image dated September 30 also failed to
recognize it.
It's an Inspiron 5755. dmesg(8) shows nothing. dmidecode(8)
shows it. According to Slackware, it's a Synaptics touchpad
and works with all the options on a usb bus (Bus 003 Device 004).
Slackware also indicates it's "ID 06cb:75bf Synaptics, Inc."

The contents of
/usr/local/etc/X11/xorg.conf.d/driver-touchpad.conf:

Section "InputDevice"
  Identifier  "Touchpad"
  Driver  "libinput"
  Option "Device"  "/dev/input/event6"
  Option  "AutoServerLayout"  "true"
EndSection

grep -rF 06cb /usr/src/ returns (among other things)
/usr/src/contrib/libfido2/udev/ 0x06cb Synaptics Inc.,
as well as one other related entry.

Any thoughts on how I might get my touchpad to get recognized?

Thanks
