But Rob's post mentions a combination of batteries and other power supplies??
I thought a ground loop could occur if there is a potential difference between various the negative terminals of different power supplies, e.g., between the negative terminal of a USB plug connected to a laptop being powered from a 240V adapter, and the negative terminal of a CCD being powered from a 12V battery???

Did you edit your post?? I didn't see the bit about laptops not being earthed??
