What make/model is your USB to Cat5 converter and the length of the Cat5 (or Cat6) cable. Cheaper units cannot handle the full USB2 data rate. Those from StarTech, while more expensive work without problems at USB2 speed up to their specified cable length. Image downloading is when the highest data rate occurs.

I have had similar hangs with SGP which cleared with a change of USB cable to the camera.

Ah, so your usb/cat5 looks like it's fine though no harm in swapping it for cat6. It should let it operate over a longer distance. I would try a new USB cable (Lindy or similar) on your camera to see if it gets better. ?

I always spray all my 'outside' connector contacts with ACF-50 before use which has greatly reduced any problems with bad or corroded connections. It also helps with existing contacts which have started to show some corrosion by stopping it developing further and cleaning the existing contacts.
