This is more of a heads up than a rant guys and the info may come in handy especially if you are thinking of buying the Saitek X52Pro for xmas or a present for someone else.
I've spent the last 2 months getting FSX to run as smooth as possible with about 40GB of various addons and had it running perfectly with all sorts of custom military traffic etc, I was using a CH Flight Yoke as I mainly fly the Nimrod or P3 Orion, anyway i downloaded a couple of fighters so decided to buy the Saitek X52 pro, brand new.
I downloaded the latest drivers and thats where the trouble began, a known problem i may add, but unknown to me. The result was like a virus sweeping through my system, none of my games would work, the PC kept freezing and hanging, all sorts of crap going on.
The solution was the drivers were conflicting with my Z87 motherboard, not sure if it conflicts with other MOB's, but the fix is:ti disable xHCI in BIOS which means that all USB port will operate at USB 2.0, this fixed the solution however i had to uninstall SF2, FSX, DCS and then reinstall them all. Now the X52Pro works brilliantly, but what a ball ache, should've just bought a Thrustmaster Hotas X for £30 and been problem free.
Anyway, just thought i would share as it took me 4 hours of solid googling etc to find a fix.
