Although Logitech Quickcam is said to be compatible only with System 9.0.4- 9.1, it's also very easy to use with 9.2.2.
You need first to install your Logitech Qucikcam Pro 3000 software (version 5.0, on the cd).
Open the System Folder- Extensions folder and remove the extension Philips USB Cameras, 1.1f1 version.
Download the new driver Philips USB Cameras 1.1 or go to get the latest Philips' driver and put it in the extension folder. Shut down and before restarting, plug your Quickcam' cable into your computer's USB port.
Restart and enjoy your Quickcam Pro 3000! It works fine with System 9.2.2 - not yet compatible with MacOs X and Classic.
