[vox-tech] linux force-feedback devices

[John Wojnaroski]

Hi,

need some help/info from anyone using force-feedback devices with 
version 2.6.xxx

have been using a force-feedback device with 2.4.18 with a patch for 
I-force devices

recently upgraded to 2.6.10 with built in support, however when trying 
to run the app get the following error when trying to remove an effect

Device /dev/input/event2 opened
ERROR: removing effect failed (Function not implemented) [js_ff.cxx:151]

odd, would have thought that loading and unloading are such basic 
functions that they would be included in the latest kernel.

A quick check of input.h and evdev.c shows the hooks are there for 
EVIOCRMFF, but evdev.c returns the NOSYS error.  Did I miss something 
compiling the new kernel?  Uploading and running effects works; just 
can't offload from the device to upload new effects and parameters 
beyond what is in the devices memory.  Or is there a new function to 
allow updating effect parameters without offloading?

Regards
John W.
