Subject: 答复: 答复: 答复: [PATCH] input: alps-fix the issue alps cs19 trackstick do not work.
Date: Tue, 11 Jun 2019 03:05:16 +0000	[thread overview]
Message-ID: <OSBPR01MB485504868362073ED434F82FDAED0@OSBPR01MB4855.jpnprd01.prod.outlook.com> (raw)

Hi Pali,

I discussed with our FW team about this problem.
We think the V8 method means a touchpad feature  and does not fit the CS19 trackpoint device. 
CS19 TrackPoint needn't  use any Absolute (Raw) mode and is usually use standard mouse data.
CS19 TrackPoint device is a completely different device with DualPoint device of Dell/HP.
CS19 TrackPoint device is independent  of Touchpad. (Touchpad is connecting by I2C, TrackPoint is directly connecting with PS2 port.)
And it has completely another FW. 

So we think it is better to use the mouse mode for CS19 trackpoint.

Best Regards
Shona

Yes, it is fine. Just make sure that touchapad input device is not registered when this ALPS_ONLY_TRACKSTICK flag is set. So userspace would not see any fake/unavailable touchpad input device.
