Have you checked with `lsusb`? Is it there with the proper IDs? > I suppose something could have happened to the relays or cables... Often we saw shitty USB cables. Other than that I have no ideas, but in case you will attend Kernel Recipes in Paris I can bring a new one to you. I'm not sure about LPC, though. Ah, one thing is the eMMC that theoretically can go away. But I never heard of a such in conjunction with Intel Edison. -- With Best Regards, Andy Shevchenko
