we want to connect 3 USB Macally cameras to our computer, and use the live video input using the jit.qt.grab object. When connecting the cameras through a powered USB hub, the cameras are detected. But when selecting the input, only the first camera works. The other two get an automatic name Macally #2 etc but when selected, these do not work. Anyone has got experience with the connection of multiple USB cameras to Jitter? I found some older forum discussion, but these mention firewire cameras. Thanks!
