I believe you can use the code in a product as long as the product =20
uses a microchip microprocessor. Adapting the Microchip USB stack to =20
an Atmel USB controller would get someone annoyed.

This of course means that the CDC implementations for PIC, Atmel, TI, =20
Silicon Labs, Cypress, etc all have different bugs.  Which is why I =20
was thinking that the world would be ripe for a common implementation.

(The Microchip CDC Serial port seems to work reasonably well, FWIW.  =20
The EggBot uses it and AFAIK hasn't had any USB-related problems on =20
any of windows/linux/mac...)
