LUFA (Lightweight USB Framework for AVRs, formerly known as MyUSB) is my first foray into the world of USB. It is an open-source complete USB stack for the USB-enabled Atmel AVR8 and (some of the) AVR32 microcontroller series, released under the permissive MIT License (see documentation or project source for full license details). The complete line of Atmel USB AVRs and USB AVR boards are supported by the library, as are any custom user boards, via custom board hardware drivers supplied by the user.

There also seems to be a LUFA port to the NXP IC that we are planning to use in the "tomu pro" board - https://www.lpcware.com/content/project/nxpusblib and https://github.com/kevinmehall/LUFA-LPC13xx

(Not LUFA, but still related) - if someone is looking for an open USB stack I ported the libopencm3 USB stack & examples - see here: https://groups.google.com/d/msg/tomu-discuss/N3lDA_wuFTo/oUM6Qi5zAgAJ
