mouse resync messages since 2.6.15-rc2-mm1, still in 2.6.15-rc3-mm1

mouse resync messages since 2.6.15-rc2-mm1, still in 2.6.15-rc3-mm1

[jurriaan]

I access my workstations with a KVM switch, a Rose Vista model, and
since 2.6.15-rc2-mm1, I get an awful lot of

logips2pp: Detected unknown logitech mouse model 1
psmouse.c: resync failed, issuing reconnect request

messages. What is the information content in these messages? I take it
they tell me something important - but I can't understand what. If they
are just noise, could they please be removed?
I know my mouse works when I switch consoles; this KVM has worked for
ages with linux. 

I can always #if 0 them out myself, but I'm curious what the meaning of
these messages is.

Thanks,
Jurriaan

smoke gathering under the ceiling, that didn't seem as crucial somehow.

You not supposed to see thiese messages. When you boot, what mouse type
does the kernel detect? Could you send me your dmesg please? Also, if
you could do:

1. echo 1 > /sys/modules/i8042/parameters/debug
2. Switch your KVM to another box
3. Wait 5 seconds
4. Switch back
5. Move the mouse slightly
6. echo 0 > /sys/modules/i8042/parameters/debug

... and send me dmesg I would appreciate it.

You can disable resync mode by doing:

	echo -n 0 > /sys/bus/serio/devices/serioX/resync_time

where serioX is serio port your mouse is connected to.
