So, I recently picked up an original iSight camera (the barrel shaped one). Its got a FW400 cable on it, but I picked up a 400-800 adapter. I tried plugging it into my mid-2012 cMBP, but it does not work (I use my computer in clamshell mode with an external monitor and keyboard and mouse). I would like to get this working, has anyone ever managed to make it happen? I checked the camera on my G5 system, and it works perfectly on it via FW400. With the FW800 adapter, I can get the little green light to come on for a second, and can hear it focus, but thats all that it will do with my newer MBP. Thanks for any help.
