I currently have a Trackman Marble FX mouse working on an XP computer using the PS/2 port. Can I make it work through the USB port by just getting a adapter and using the old software or do I need to get a USB driver?
There are generic PS/2->USB adapters that have their own USB drivers and add an emulated set of PS/2 ports to your PC, which may work with the Trackman Marble FX. If the adapter does a good job, the emulated PS/2 port would work with the Trackman Marble FX's normal PS/2 driver and you would get full functionality. If it does a poor job, some of the buttons might not work.
Logitech doesn't manufacture or support generic PS/2->USB adapters such as this, so it would be up to the manufacturer of the adapter to provide you with any support. These adapters can be found at most PC supply stores for about 20$US. I have no idea how well they work.
