Dear all, I am a hobbyist located in Germany and planning to sell a few USB devices based on the Atmel AT90USB uC series. Other than the crystal oscillator (@8MHz) and some I/O pins, there is not much RF going on, and it comes in a metal enclosure. Now I am not sure whether this kind of device would require FCC authorization in order to be imported to the US or Canada. I went through the regulations, but I could not quite figure out a correct way to handle this. Anyone? Thank you, Matthias
