+ * - XMEGA Architecture
+ * \warning The XMEGA device support is currently <b>experimental</b> (incomplete and/or non-functional), and is included for preview purposes only.
+ *
+ * - No demos, bootloaders or projects have been ported for the XMEGA devices in the current release,
+ * although the architecture is supported in the LUFA core library.
+ * - Endpoints of more than 64 bytes are not currently supported in this release.
+ * - Isochronous endpoints are not currently supported in this release. As a result, the audio class
+ * cannot be used on XMEGA devices.
+ * - Multiple-bank endpoints are not currently supported in this release.
+ * - Early revisions of the ATXMEGA128A1U are incompatible with LUFA, due to their various errata
+ * relating to the USB controller.
