I have a STL-1001 USB camera which I am trying to use on a brand new Mac Mini (running Yosemite). I installed the latest SBIG drivers and CCDops-Lite. The camera works fine under Windows and Linux. On the Mac, I get "No device found" or something to that effect. But if I first plug the camera's USB cable into the Windows machine then switch it back to the Mac without powering down, the camera is recognized and works perfectly. My conclusion is that on the Mac, the EZ-USB chip in the camera is not getting its firmware loaded. When I tried the Linux Dev Kit, I got the same kind of error (device not found) until I installed the fxload utility. (This utility is required, but not mentioned in the docs.) I'm wondering if there is another such dependency on the Mac platform. Maybe the newer Macs are missing something ?
