Subject: about mouse lost synchronization
Date: Wed, 13 May 2009 15:27:33 +0800	[thread overview]
Message-ID: <000001c9d39c$4baeb6f0$e30c24d0$@org.tw> (raw)

Dear all

I've implemented a ps/2 serio driver that uses GPIO (two GPIO pins). Each 

bit is triggered by GPIO interrupt. When in console mode, GPM works

fine, and I can see the mouse cursor moves correctly. But When entering 

GUI, say QT or microwindows, the following messages occurred:

Mouse at xxxxx/serio0/input0 lost synchronization, throwing 1 bytes away.
..
Mouse at xxxxx/serio0/input0 lost synchronization, throwing 1 bytes away.

Mouse at xxxxx/serio0/input0 lost synchronization, throwing 2 bytes away.

And the mouse cursor is floating and moves incorrectly. 

What is the criteria that kernel think the mouse packet is lost of sync.?

                                        Regards,
                                                ycchang
