I also have a Point Grey camera (GS3-U3-51S5C-C), but I could not get PHD2 to detect my camera.
"Windows WDM-style webcam camera" option is selected, and I am using a USB3 connection.
I tried different ports; restarting my pc after each change. Both Spinnaker and FlyCap drivers are installed and both can detect the camera just fine.
Any suggestions? Thanks.
I'll share my experience with the 23S6M to see if anything might be useful. I'm using phd2 version 2.6.9. It almost always causes phd2 to crash when I go to connect the camera the first time (something about initiating the driver maybe?) but when I reboot phd2 it connects without any trouble.
One thing you might check if you haven't already is the "Select which camera..." icon (looks like two divergent arrows) next to the camera selection box that highlights when the WDM option is chosen. After I specify the point grey camera in that box I get another box that gives me a ton of camera mode options. I've not played around with them all, but I know that the 1920x1080 30fps option worked for me. Many of the others either wouldn't connect or would connect but wouldn't actually function within phd2. Of course if it isn't recognizing the camera at all you might not even have those options.
I can't recall if I updated the firmware on my camera but that might be another option for something to try.
