Scott Shawcroft 8f26d181c3 Blinking the LED works. Clocks should be set up correctly.
Everything works fine without USB being plugged in but faults (I think) when USB is plugged in. This is switched away from the USB code from the bootloader onto the USB code thats generated by Atmel Studio using the high level classes from ASF.

*
* The Universal Serial Bus (USB) module complies with the USB 2.1 specification.
*
* The following peripherals are used by this module:
* - USB (Universal Serial Bus)
*
* The following devices can use this module:
* - Atmel | SMART SAM D21
* - Atmel | SMART SAM R21
* - Atmel | SMART SAM D11 (Only USB device support on SAM D11 device)
* - Atmel | SMART SAM L21
* - Atmel | SMART SAM L22 (Only USB device support on SAM L22 device)
* - Atmel | SMART SAM DA1
*
* The USB module covers following mode:
* \if USB_DEVICE_MODE
* - USB Device Mode
* \endif
* \if USB_HOST_MODE
* - USB Host Mode
* \endif
*
* The USB module covers following speed:
* \if USB_HS_MODE
* - USB High Speed (480Mbit/s)
* \endif
* - USB Full Speed (12Mbit/s)
* \if USB_LS_MODE
* - USB Low Speed (1.5Mbit/s)
* \endif
*
* \if USB_LPM_MODE
* The USB module supports Link Power Management (LPM-L1) protocol.
* \endif
*
* USB support needs whole set of enumeration process, to make the device
* recognizable and usable. The USB driver is designed to interface to the
* USB Stack in Atmel Software Framework (ASF).
*
* \if USB_DEVICE_MODE
* \section asfdoc_sam0_usb_device USB Device Mode
* The ASF USB Device Stack has defined the USB Device Driver (UDD) interface,
* to support USB device operations. The USB module device driver complies with
