Hi DataCommando, thank you for your reply. FYI I read the manual whenever I need it (if I need it at all), and if I posted the question it is because my Helix Floor has been connected to a USB3 port since I purchased it and it has always worked!!! However, this morning in trying to upgrade from 3.70 to 3.71, both the Editor and the Updater would not work. The updater in particular had started loading the firmware when suddenly the following message appeared: AN ERROR HAS OCCURRED. PLEASE TRY AGAIN. At that point the Helix no longer responded to the Boot and so I attempted to restore it by performing the procedure from the manual. Unfortunately, there was nothing to be done despite changing the PC, (using a laptop that has only USB2 ports). Only then did I plug the cable into the USB2 on the PC and everything was restored. Magic? Miracle? I don't know. So save the "unbelievable" quip. Before you set yourself up as a know-it-all, it would have been nice to have an exchange of views from serious people. Anyway thanks again for "your technically superior answer" however do me a favor, if I still need some advice, you don't give me any. Good luck for everything
