You may want to check if that Vista 64bit machine has been set up
to block unsigned driver package? Take note libusbk.sys has
been signed but the whole drive package is not (since that is for
your specific VID/PID).

Another thing to try, what if you remove the cat file from both the driver
package and from the inf file?
