Hi.

The trackpoint / touchpad combo on an HP EliteBook 850 G1 is detected
under Windows 7 as:

Synaptics TouchStyk V2.0 on PS/2 Port 1
Synaptics LuxPad V1.5 on SMB Port

Linux 6.13.9 (zabbly stable kernel on debian bookworm) detects these devices as:

PS/2 Generic Mouse
SynPS/2 Synaptics TouchPad

I was unable to get libinput quirks working so I filed
https://gitlab.freedesktop.org/libinput/libinput/-/issues/1106 - Peter
Hutterer kindly explained that the problem is that linux does not set
the INPUT_PROP_POINTINGSTICK property on my trackpoint. He explained
the udev hwdb workaround and he also suggested that I send a mail to
this list.

For what it's worth, I think that this mis-detection occurs on many HP
laptop models.
