Sony Cybershot won't mount
I have a new iMac 24" and so far the only insoluble problem I have met in getting all my old stuff to work is that my Sony DSC-T1 does not mount. The computer is set to launch Image Capture when a digital camera is connected. However, when the camera is powered on, its USB display remains white instead of going red as it does when communicating with a computer, and the iMac does not 'see' it - although it is there in System Profiler/USB. There is no joy even if it is plugged directly into a USB port on the iMac itself. Any hints much appreciated.
iMac 2.8 GHz, Mac OS X (10.4.10)
