For the trackball, If it asks you for a more up to date driver, put your XP operating CD in and point it to that.
Without a link to the driver site I cannot recommend a driver for you if the above does not work.
To get a driver onto a cd (or a USB pen drive), just download them to your desktop, then right click on the icon from the download and select SEND TO from the dropdown box and then select your CD/DVD drive to burn it to.
If you want to add more files to the CD/DVD just repeat the process on the others before you select to burn them.
Once you click on the icon in the taskbar to burn them to CD/DVD a Wizard will take you through the process.
So if you are unsure which driver to load , Download them all and burn them onto one CD.
Hope that helps you.
