Hi,

The touchpad is recognised OK when the kernel boots,
and my usb
connected mouse works fine.  But I get the following
message in
the syslog when I try to use the mousepad or any of
the buttons :-

    ... kernel: Synaptics driver lost sync at 1st byte

It worked alright in previous kernels before the
Synaptic driver was
added.

Relevant /var/log/dmesg content:-

The logs from your other mail show that the touchpad is still in
relative mode (using 3 byte packets) instead of absolute mode (using 6
byte packets.) I don't know why this happens, but here are some things
to investigate:

* Does the touchpad work with the synaptics XFree driver and a 2.4
  kernel?
* Does the Synaptics aware GPM version work?
  (:pserver:cvs@ar.linux.it:/data/cvs)
* Can you add some printks to the synaptics_reset() function to see
  why it fails?
* Maybe it helps to remove the call to synaptics_reset() in
  query_hardware(). (I know this helped one user that used the user
  space XFree driver with a 2.4 kernel.)

You should use /dev/input/eventX, where X is a number that depends on
your hardware configuration. My config looks like this:

Section "InputDevice"
        Identifier      "TouchPad"
        Driver  "synaptics"
        Option  "Device"        "/dev/input/event2"
        Option  "Protocol"      "event"
        Option  "LeftEdge"      "1800"
        Option  "RightEdge"     "5400"
        Option  "TopEdge"       "4200"
        Option  "BottomEdge"    "1500"
        Option  "FingerLow"     "25"
        Option  "FingerHigh"    "30"
        Option  "MaxTapTime"    "180"
        Option  "MaxTapMove"    "220"
        Option  "VertScrollDelta"       "100"
        Option  "HorizScrollDelta"      "100"
        Option  "EdgeMotionSpeed"       "40"
        Option  "MinSpeed"      "0.08"
        Option  "MaxSpeed"      "0.10"
        Option  "AccelFactor"   "0.0010"
        Option  "SHMConfig"     "on"
        Option  "EmulateMidButtonTime" "75"

OK, the problem is that the touchpad needs a lot of time to wake up
after a reset command. As we found out in private conversation, 3
seconds is barely enough, so I suggest the following patch to fix the
problem:

--- linux/drivers/input/mouse.resume/psmouse-base.c	Sat Jul  5 23:39:14 2003
+++ linux/drivers/input/mouse/psmouse-base.c	Sun Jul  6 00:23:17 2003
@@ -201,7 +201,7 @@
 	psmouse->cmdcnt = receive;
 
 	if (command == PSMOUSE_CMD_RESET_BAT)
-                timeout = 2000000; /* 2 sec */
+                timeout = 4000000; /* 4 sec */
 
 	if (command & 0xff)
 		if (psmouse_sendbyte(psmouse, command & 0xff))

Some progress.

I added a "%#x" to the printk for the "..driver lost sync.." message,
and got these results logged:-

 kernel: Synaptics driver lost sync at 1st byte(0x18)
 kernel: Synaptics driver lost sync at 1st byte(0xff)
 kernel: Synaptics driver lost sync at 1st byte(0x0)
 kernel: Synaptics driver lost sync at 1st byte(0x18)
 kernel: Synaptics driver lost sync at 1st byte(0xff)
 kernel: Synaptics driver lost sync at 1st byte(0x0)
 kernel: Synaptics driver lost sync at 1st byte(0x18)
 kernel: Synaptics driver lost sync at 1st byte(0xfe)
 kernel: Synaptics driver lost sync at 1st byte(0x0)

Pressing one of the left buttons gives:-
 kernel: Synaptics driver lost sync at 1st byte(0x9)
 kernel: Synaptics driver lost sync at 1st byte(0x0)
 kernel: Synaptics driver lost sync at 1st byte(0x0)

and releasing it:-
 kernel: Synaptics driver lost sync at 1st byte(0x8)
 kernel: Synaptics driver lost sync at 1st byte(0x0)
 kernel: Synaptics driver lost sync at 1st byte(0x0)

while wiping a finger across the pad:-
 kernel: Synaptics driver lost sync at 1st byte(0x8)
 kernel: Synaptics driver lost sync at 1st byte(0x1)
 kernel: Synaptics driver lost sync at 1st byte(0x0)
 kernel: Synaptics driver lost sync at 1st byte(0x8)
 kernel: Synaptics driver lost sync at 1st byte(0x3)
 kernel: Synaptics driver lost sync at 1st byte(0x1)
 kernel: Synaptics driver lost sync at 1st byte(0x8)
 kernel: Synaptics driver lost sync at 1st byte(0x2)
 kernel: Synaptics driver lost sync at 1st byte(0x0)
 kernel: Synaptics driver lost sync at 1st byte(0x8)
 kernel: Synaptics driver lost sync at 1st byte(0x2)
 kernel: Synaptics driver lost sync at 1st byte(0x0)
 kernel: Synaptics driver lost sync at 1st byte(0x28)
 kernel: Synaptics driver lost sync at 1st byte(0x3)
 kernel: Synaptics driver lost sync at 1st byte(0xff)
 kernel: Synaptics driver lost sync at 1st byte(0x28)
 kernel: Synaptics driver lost sync at 1st byte(0x2)
 kernel: Synaptics driver lost sync at 1st byte(0xff)
 kernel: Synaptics driver lost sync at 1st byte(0x8)
 kernel: Synaptics driver lost sync at 1st byte(0x4)
 kernel: Synaptics driver lost sync at 1st byte(0x0)
... (lots more)

It looks like the protocol is three bytes per 'event' and the nibbles
have been swapped in the bytes from this touchpad!

Mike.
