Hi
I'm having a real tear-my-hair-out day.
Quick background. I have 2 MBP 2.5G machines. They were both bought the same day from the same store while on holiday in the US.
Now, I've never actually used my iSight on my first MBP, until 3 days ago when I needed to use it.
I fired up the application, and I got a black screen where the picture should be.
Now, the second MBP has no problem whatsoever, so I compared System Profiler entries.
Both of them are "MacBook Pro 4,1"
In the USB section, the one with the WORKING iSight lists version 1.60, Product ID and Vendor ID are correct (0x8502 and 0x05ac).
On the working MBP, the serial number for the iSight looks legible and correct.
The details on the broken iSight MBP are EXACTLY the same vesion, product and vendor ID, but the serial number is a bunch of garbled characters.
This leads me to believe that there must be something wrong with the firmware.
My problem is that my MBP is already at 4,1 version so I can't find the firmware ANYWHERE and there is no restore firmware anywhere.
I re-installed Leopard (10.5.2) on the MBP and the problem remains.
I read that Boot Camp may update the firmware, but no joy - in Windows XP (I HATE having to pollute my Mac with Windows) through Boot Camp I have the same problem, but also drivers won't install in Windows for the trackpad or iSight - instead I have generic HID mouse and generic USB video device.
Now the Operating system thinks they are working fine, but the iSight doesn't fire at all.
Does anyone know a way to restore the firmware, or even downgrade it so that Software Update can apply the firmware update again?
