+ * These are the known alternative USB stacks which can run on regular AVR models, lacking dedicated hardware USB controllers
+ * via a bit-banged (emulated) version of the USB protocol. They are limited in their capabilities due to the cycles required
+ * to be dedicated to managing the USB bus, but offer a cheap way to implement USB functionality into a design.

+ * <b>Description:</b> Atmel's official software USB implementation, an Application Note containing work by Igor Cesko. This
+ * is a minimal assembly-only implementation of software USB, providing HID functionality. Less compile
+ * options than V-USB (see below).

+ * <b>Description:</b> Well regarded and complete USB 1.1 software stack for several AVR models, implementing Low Speed HID.
+ * Used in many commercial and non-commercial designs, with user-submitted projects available for viewing
+ * on the company's website. Uses C language code mixed with assembly for time-critical sections.
