Could someone point me to information on how to change a 32bit usb serial driver to 64bit. It works under W7 x86 like it is. Any help would be appreciated. D This is the .inf file I'm needing to install under x64 windows.

You can't just rewrite an INI file to make it 64 bit. All the files associated with the driver have to be compiled in 64 bit, so unless you have the actual sources, you get nada.
