When connecting the NExto Extreme 2700 to a Sony EX1r, I get the following error on the Nexto screen:
then it shuts down. I am at firmware v1.08. I have good USB cables (tested). When I turn on Nexto (or plug in USB after Nexto is powered on), the camera says "USB Mode" and I say 'Execute'. Then I get the error (above) on the Nexto.
