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
