I know there have been some people here that have been trying to get CCV 1.5 to work with the PS3 Eye on a version of Windows 8. After a lot of trial and error and some waiting, I was able to get it working this morning!! I now have 2 PS3 Eyes working in CCV 1.5 on Windows 8 Release Preview.
To get it to work, you need to use one of the newest version of the CLEye Driver because they support Windows 8.
Next, remove any version of the CLEye SDK and install the newest version (V1.4.0.0230) which was released earlier this month.
PS3 Eye SDK Link
After it is installed, go to the SDKs Bin folder C:\Program Files\Code Laboratories\CL-Eye Platform SDK\Bin
Copy the CLEyeMulticam.dll file.
Paste the file into the CCV 1.5 folder and overwrite the old one.
Plug in your cameras and after they are detected, launch CCV.
Once I did this, CCV 1.5 launch successfully and I am now able to use both cameras on Windows 8. I hope this helps anyone else that has been trying to figure this out.
