Subject: [PATCH] Input: ALPS - Recognise "Dolphin V2" touchpads
Date: Mon, 6 Jan 2014 20:10:34 +0000 [thread overview]
Message-ID: <1389039034-14040-1-git-send-email-chris@diamand.org> (raw)
This is the touchpad used on the Dell Vostro 3360. Without
this change, the driver reports this as follows:
psmouse serio1: alps: Unknown ALPS touchpad: E7=73 03 50, EC=73 02 02
It seems to use the ALPS V5 protocol, so identify it
as such by allowing ec[1] == 0x02.
This is based on src/alps.c from the DKMS driver here:
