How to setup trackpoint sensitivity for external devices?

[gauthier]

Hello,

I've just got a "vintage" model m keyboard featuring an integrated trackpoint, but my concern is the fact that while using it on with my laptop, I can't set the sensitivity for the external keyboard's trackpoint.

The keyboard is attached via a 2 * ps2 => usb adapter, and I don't know a way to set parameters for every independant pointing devices.

Do you know some utility that will achieve the purpose?

Thanks!
