Atmel SAM3x USB MIDI help

Hi friends. I need help with enumeration. I have the correct structure for the descriptors (per the USB standard) but I don't know the secret incantation to make it go, and I've had no luck cribbing from the ASF implementation of HID/MSC/whatever other class due to my beginner-level C++ and ASF's intense level of portability obfuscating the answer. SAM-BA is working, SPI is working... buttons are even working! so that's something.

I need udc_start() to actually work.


I've seen claims of a LUFA port to ARM but can't find it for SAM3x.


Any suggestions are welcome, thanks!
