I use the 7.0.53.6 64bit drivers which are the newest MadCatz ones. Is that still an issue with the x-52 pro? in the end, i got everything working properly, but only by using a previous version driver. i had to sort my way through various versions till i came across the last win 7 version that was still signed properly (by Saitek). Don't know if the situation has changed since i last dealt with the issue, but last time i had out my x-52 pro, i ended up having to dig around for previous versions of the driver software, because the 'new' madkatz signed drivers were Improperly signed and were getting blocked by windows.
I already have the drivers and software installed, so it should be as easy as plugging it in. I will have to go get mine and try it out to see what it is like. You use your x-52 pro with ksp? I had never even considered using mine for this game.
