Hi, I got the almost the same setup as you (ps2 touchpad on dell i8k + usb logitech). Since 2.6.0-test1, /dev/psaux is used by me usb mouse. /dev/ input/mice (for usb in 2.4.x) is use by both. If you cat /dev/input/mouseX, you will find your ps2 mouse on mouse0 and usb on mouse1. Nic Cola -- A modem is a baudy house.
