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.
