I am not sure what you meant by specially made for Sony or any other brands. Usually the drivers are being giving to the manufacturers, and it depends on them to repackage the drivers and make them available to users.
If Sony Support site does not show the drivers for XP, then the best bet is listing out the devices, and then search them at the drivers manufacturers sites.
You can list them out here also, we can all chip in for the searches.
