Or maybe a combination of both? It showed up once before - co-incidentally when I was cooling the cam and shooting flats - but it went away quickly last time - maybe as the ambient temp was higher last weekend it took longer to stabilize the cam? Some other folks here have also raised some interesting USB options.

Couls be, I usually use a powered USB hub. I removed it as well during the diagnostics and chose not to use it after that when the cam was working again

...and there you go! So it could well be cooling related
Time to drag it out and do a few more tests methinks.
