You shouldn't need the driver just to send commands to the device, AFAIK. I am actually using this on Mac OS X also. I am using libhid to actually avoid using the drivers. As far as I understand it, with libhid, I can just send the commands directly to the device, and it should rumble. A friend has this working on Windows (not using libhid but the Windows DDK). I think the drivers provide a separate API for Force Feedback. On Mac OS X, the driver is needed to use the Immersion API, for example. .hc ------------------------------------------------------------------------ ---- "[W]e have invented the technology to eliminate scarcity, but we are deliberately throwing it away to benefit those who profit from scarcity." -John Gilmore _______________________________________________ libhid-discuss mailing list [email protected] http://lists.alioth.debian.org/mailman/listinfo/libhid-discuss
