The Space Traveler is a device we have not produced for over seven years. It was never a device that the Mac operating system ever made use of. The last driver ever made for it was 3DxSoftware 3.7.22. Windows 7 had not been invented yet, so that set of drivers are only for XP and Vista for applications back in that time frame. You may find this driver by doing a search for the SpaceTraveler with 'Also show archived software' box checked on our 'Driver Download' Page under the 'Service' Menu.
The more things change, the more they remain the same. ; ^ )
