Interesting - at first I got no response for a couple of the permuations
I had tried before - so I tried a new permutation of USB port and two
cables - an extension cable connected to a std USB cable with a micro
plug - which worked! Now I am confused about why ALL the other
permutations worked for ALL the other devices - besides the camera . .
weird - maybe it is an intermittent cable or camera problem? - hmm . .
more testing required . . at least I know now that the connection is not
100% failed . .
Thanks for responding - I appreciate it!
Glad your camera is still alive. Cables and connectors should always be a
prime suspect when things stop working. Having worked at an oceanographic
institute, salt air and cables is not a good combination. Cables and
connectors are vulnerable to damage from corrosion and vibration.
Cheap cables are also prone radio-frequency interference (RFI). You
can buy "contact enhancer" fluid such as "Stabilant 22" (used in aviation
and increasingly used by automakers and auto repair shops -- I'm in
Canada and Stabilant 22 is now sold by auto parts stores here).
USB3 uses signals that can cause RFI with older equipment.
I find that older USB2 devices are often more reliable when used with
an external hub so not connected to a socket on the back of a system
next to one being used by a USB3 device.
