I've got a serial trackball hooked up to my girls' computer because a) a trackball is easier for them to use and b) it's got LEDs in it that light one color (I changed to Pink) most of the time and another (I plan on changing to UV) when you click any of the three buttons.
It's giving me some trouble though which is why I'm coming to the place with all the answers!

To make the trackball work you have to move the ball during startup. Here's how it goes.
First, when I do nothing.
I hit the power button, about 20 seconds pass then the LEDs blink twice, just a quick blink and then they stay off.
And to get it to work...
I hit the power button, about 20 seconds pass 'till the LEDs blink the same twice but this time I'm moving the ball. Starting to move it just a few seconds before they blink is enough. So it blinks, yea, then off for a second or two then two more blinks followed by a second or two off then the LEDs come on and stay on at the same time the WinXP logon screen comes up.
I'm at a loss here. I even went and bought a serial to USB adapter but that doesn't seem to work from a boot or hot-plugging.
I suppose I could scratch the idea of using this trackball and either use a different one or a mouse but I like the LEDs and the overall look of the trackball so any help would be appreciated.
