W7 and DirectX 11

I build my own joystick, rudder pedals and throttle unit.
Modeled after a Spitfire stick and a P-51 rudder pedals.
I first used them on my XP Pro puter, now on my new puter.
In game, the 4 momentaries I have on the joystick seem to have intermittant failures. I have replaced the momentaries, I have replaced the USB module, thats the "plane brain". Still get a button failure at critical times in game.
In game control settings they always work. No issue with XP.
Only difference between then and now is the OS, XP Pro SP3 > W7 and Direct X version, 9.0c > 11.
Any thoughts to what I can check?
DXDiag shows "no problems found".

I dont know much about this type of setup, but it seems as though your drivers or hardware aint making it with WINDOWS 7. What you can do is either find W7 compatible drivers, or, perhaps you should try installing XP drivers in compatibility mode to avoid a OS MISMATCH error if they wont install normally - perhaps this would work with your older setup? I dont know. This is how you do it - if you can do anything with it I dont know:

To install a driver OR program in compatibility mode - right click the setup.exe file - click properties - click compatibility - check run in compatibility with vista/xp etc - check run as administrator - leave the rest blank. Start setup.exe and install.

Link to kb site - it also has info on locating the inf. thru device manager to install drivers.
You cannot install a device driver by using its installation program in Windows Vista

You can also run the software in compatibility mode after installation :

To run a program in compatibility mode after installation - right click a short-cut to the program, or find the program in program files and do likewise - click properties - click compatibility - check run in compatibility with vista/xp etc - check run as administrator - leave the rest blank. Start the program.

No drivers, I plug it in an go. Whatever drivers would all be W7 stock drivers.
Do USB ports get throttled some how? I have turned off any save energy options. Plus as I said, they always function in game controller settings.
Thats why I was wondering about DX11.
What would happen if I installed DX 9.0c? Would I corrupt DX11 in any way?
Its an older game and only uses DX8.1 or 9. I realize that DX is suppose to be backward compatible.
I did look at using game in compatability mode but XP is not in the available choices. Game seems to run fine, tho. Except of course the momentary issue.

You can install direct x 9.C updates -w7 runs both 9.C, 10 and 11 depending on what the application supports:

You could try updating your chipset drivers to the latest - http://downloadcenter.intel.com/default.aspx

I will try the DX 9 updates.

I am currently using Intel Chipset ver. 9.5, is there a later one?

This is the latest chipset driver to my knowledge 12/22/2009 v9.​1.​1.​1025
INF Update Utility - Primarily for Intel® 5, 4, 3, 900 Series Chipsets

Version 9.5 - are you refering to intel rapid storage driver - If so version 9.6.0.1014 is available here :
RAID: Intel® Rapid Storage Technology Driver for Intel Desktop Boards

I see you have raid - so its up to you I guess - i was having some problems with the rapid storage manager myself, but i think it was related to other software - after I renamed a drive in w7 and went to vista on another partition where I have Paragon backup installed vista then couldnt recognise the drive, so i just assigned a drive letter to fix it.

just writing to say that is one AWESOME stick setup - first time i've seen a stick modelled on a spit's ringed control :)

afraid i have no suggestions re: the stick / usb error issue...

OOps,
9.5 was the storage driver, which I had already updated to 9.6 RST.
I am using the latest chipset driver, 9.1.

So,
Its possible adding DX 9 might of helped, did a brief test offline and..................................
Real test is online in combat, post about it later.
