Wrong Synaptics Touchpad detection when USB mouse present

[Mattia Dongili <dongili@supereva.it>]

Hi,

[Please Cc me as I'm not subscribed to the list]

I'm experiencing problems with a dual configuration of mice on my
laptop. The sympthoms are:

- if I boot with my Logitech USB mouse plugged in, the Synaptics
  Touchpad is not recognized as such but as "PS/2 Generic Mouse"

- if I boot without USB mouse plugged in or if I simply reload psmouse
  after the boot process, the Synaptics Touchpad is recognized correctly

So it has something to do with the order modules are loaded.

I'm available to test patches and/or send more info.
I have some evidences of those facts:
---> /proc/bus/input/devices

  usb mouse present during boot
    I: Bus=0011 Vendor=0002 Product=0001 Version=0000
    N: Name="PS/2 Generic Mouse"

    H: Handlers=mouse0 event1 
    B: EV=7 
    B: KEY=70000 0 0 0 0 0 0 0 0 
    B: REL=3
