The Sony camera manual has some truly astounding weasel-wording. It starts with "The above Os must be installed at the factory", goes on to say that it may not work on upgraded OSes, in multi-boot environments, with two or more USB devices connected, or when using a hub. It then finishes with the incredible "Operations are not guaranteed for all the recommended environments listed above." I have a non-factory installation, user upgraded, multi-boot, multiple USB devices and am using a hub. XP reads it just fine. I eliminated the multiple USB devices and the hub. Linux still doesn't see the camera as a valid block device. I've had a previous experience where a camera said a card was unreadable, but a memory card reader/PC combo read it fine. I suspect the camera's programming isn't up to snuff. I'm going to watch the ads for a "deal" on an appropriate reader--I suspect that will work. If anyone has suggestions, I'll be happy to give them a try. -mj- Mark Jarvis wrote: > > The camera is a Sony DSC-W1 with a 256MB Memory Stick.
