...i am a little bit in a hurry.
Done this for you (the linked site require register to see):
BTW - Notice to "Target'ers": (Real Simulator) TUSBA adapter is not TARGET compatible!
Bluedeath: If like me you do not have the tickbox "reverse" on the throttle axis there is no need to rewire your throttle (sine i have an hall mod i would not have been able to do that anyway).
There is a quick solution that uses ppjoy and ppjoyjoy:
1 )turn your system in test mode ( i have win7 x64 dont know if this is needed for other OSes) bu opening an elevated prompt and typing : "Bcdedit.exe -set TESTSIGNING ON"
2) restart and install the software (you might have to restart the machine at the end).
3) in "control panel start "Parallel Port Joysticks (32-bit)" click on "add" and configure the joy as you see in the picturesimage upload with previewimg hostwindows 7 print screen
then start ppjoyjoy and set it up like this:free upload image
save the .ini file with a name that you like ( you will need to load it before starting Falcon) and click on "set" (you can use a shorter time but 25 ms is smooth enough) leave ppjoyjoy running in background
If you have done everything well when your TUSBA is like this:host image online
your virtual throttle will be like this: image uploading site
now open falcon and assign the virtual controller as throttle.
Have fun kids.
