Then I cloned LUFA and started trying to adapt an example to work for my board. Unfortunately, disaster struck: I accidentally tore off the USB connector. I knew this was a risk, since I decided to delay soldering the USB jack shield until I knew what to do with it. The cable I used required fairly high force to remove, though, so I think once I plugged it in the board's fate was sealed. You can also see that leftover flux greatly sped up oxidation, leaving spots of green copper oxide.  @@ -80,6 +80,8 @@ Rather than deal with jumpers again, I thought I'd fix the manufacturing.
