I have bought a FEZ Hydra and after I couldn’t connect to my computer (thinking that I burned it due to connecting wrong the USB module) I bought another one but this one is not working either.
I also have FEZ cobra II and two G120 modules, but all are experiencing the same issue.
The problem is when I connect them to my computer using USB, they appear on devices and printers, but a minute later they disappear, then appear again and go off again and the cycle is repeated all the time.
I tried with a USB power hub, even bought another computer thinking that something is wrong with my USB in my computer, but still get the same problem.
The thing is that my Netduinos and my Arduinos work without any issue.
