/* Set up force-feedback on devices that support it. This is just a stub
|

|
for the time being, since we don't yet know how the serial port force
|
||
|
feedback protocol works.
|
||
|
|
||
|
I'm currently developing with an Xbox One Thrustmaster TMX wheel, if
|
||
|
we don't perform at least some perfunctory FFB initialization of this
|
||
|
nature (or indeed if no DirectInput application is running) then the
|
||
|
wheel exhibits considerable resistance, similar to that of a stationary
|
||
|
car. Changing cf.lMagnitude to a nonzero value does cause the wheel to
|
||
|
continuously turn in the given direction with the given force as one
|
||
|
would expect (max magnitude per DirectInput docs is +/- 10000).
|
||
|
|
||
|
Failure here is non-fatal, we log any errors and move on.
