Bug ID: 233875
Summary: Dell Inspiron 13 7353 Touchpad Detected as Generic
PS/2 Mouse
Product: Base System
Version: CURRENT
Hardware: amd64
OS: Any
Status: New
Severity: Affects Only Me
Priority: ---
Component: kern
Assignee: ***@FreeBSD.org
Reporter: ***@protonmail.com

Output from /var/log/messages:
psm0: <PS/2 Mouse> irq 12 on atkbdc0
psm0: [GIANT-LOCKED]
psm0: model IntelliMouse, device ID 3-00, 3 buttons
psm0: config:00000000, flags:00000008, packet size:4
psm0: syncmask:08, syncbits:00

I put these in /boot/loader.conf:
hw.psm.synaptics_support=1
hw.psm.elantech_support=1
hw.psm.trackpoint_support=1

It still doesn't detect the touchpad. When it is detected as a generic PS/2
IntelliMouse, the multitouch gestures like two-finger scrolling does not work.
