Hi
I just finished building my Preenfm (PCB R6). I didn't know the USB key was required to work, so I just grabbed the first (and only) one I had in my drawer. It seems to work if I connect it after powering on the unit. But if I turn the Preenfm off and plug it back, sometimes the USB key is not detected and I get the message "Insert Usb Key". If I disconnect it and reconnect it, it is detected and the unit runs fine.
I'm powering it from the USB port. My guess is that the powering sequence of the unit is not happening such my USB key is ready or working by the time the Preenfm reads it. I was wondering if you have seen a similar problem.
I'm going to try to find other USB Key and check it.
