I am currently running mandrake 10 and use a track ball or a mouse with the computer. When the computer boots up with just the trackball (PS/2) or mouse(USB), which ever one was plugged in works.

For me to have both the track ball and mouse available and working, I have to boot the computer with the PS/2 trackball in and then plug in the USB mouse after boot-up.

If I boot-up the computer with both attached, only the USB mouse will work.

How can I make the PS/2 trackball and USB mouse both work straight away after boot-up?

Have you tried configuring your X config to have both of them hooked up?

I don't know what the USB mouse configuration is. I have a PS/2 and a Serial mouse hooked on my computer and they are setted up to run on my computer.

Everything for the serial mouse on my computer is configured and I setted the Identifier of the serial mouse to "Mouse2"
Then on the very bottom, for the "ServerLayout" section,
i have my mouses setted up like this :

InputDevice "Mouse1" "CorePointer"
InputDevice "Mouse2" "SendCoreEvents"

Maybe it could be configured to be something like that. Just that the USB mouse is CorePointer and trackball could be the CoreEvent sender.

I don't remember correctly though, but if you're using the 2.6.x kernel in Mandrake 10.0, there's a option for using a USB and PS/2 mouse in the Mandrake Control Panel.

in Mandrake 10.0, there's a option for using "ANY PS/2 & USB mice" which is my current setting. I will try you other ideas.

I tried something along the ideas of http://www.linux-sxs.org/hardware/dualmice.html but failed
does anyone have any ideas for me?
