Wrong Synaptics Touchpad detection when USB mouse present

Wrong Synaptics Touchpad detection when USB mouse present

[Mattia Dongili]

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

Load the USB modules first. It's your BIOS intervening. Or disable USB
Mouse support or USB Legacy support in the BIOS.

Unfortunately I have no such options on my bios (Sony Vaio GR7/K -
PhoenixBIOS 4.0 Release 6.0 - R0208C0).

Anyway I solved this problem loading uhci_hcd + hid before
psmouse in /etc/modules

Thanks for your help
