J'ai installer le driver, mais même le driver ne détecte pas la souris... j'ai déconnecter et reconnecter.
Try resetting it.
Unplug from USB jack. Hold down both buttons at the same time and plug it back in.
Try what Andy has suggested and if that does not work try the following:
Go to 3DConexxion web site and down the latest drivers for your device and make sure they are the drives for soildworks year and OS.
Un install the current drivers you have on your work station for your device.
install new drivers you downloaded
re start computer.
unplug from USB and pug it in to a different USB Port, this has worked for me in the Past.
