This may help others so I thought I pass it on.
the problem was that after a reinstall the multi panel buttons did not work or simply worked incorrectly. Also the radio panel buttons did not work. I tried everything. I had used the Logitech plugins etc.
Nothing cured this button problem. then installed original SPAD which worked but the FLAPS switch did not work correctly. Installing Spad.Next, no doubt an excellent product seemed too steep a learning curve for what I was trying to achieve, to get the panels working as intended out of the box. I even tried the Power assist thing you may read about.
Beginning to ring a bell with anyone?
Then I had a thought. Saitek never needed drivers. The panels were always driven by the Microsoft USB device drivers.
So playing that hunch I used Geek ( an essential tool in my opinion if you want to PROPERLY uninstall stuff) and uninstalled all the Saitek/logitech stuff I came across EXCEPT the direct output stuff for the instrument panel which always worked fine. So I removed something called 'flightpanels' from logitech and the plugins from logitech.
Then reboot and indeed the Microsoft USB handler picked up the panels and all now works exactly as it should.
I am using Windows 7 64 bit. All panels are plugged into the PC none in hubs.
I have seen several posts where people have struggled with the multi panel buttons not working.
so this is how I solved the problem.Maybe it helps others.
