The source code to the arduino-usbserial -project includes Atmel's VID and a PID donated by them to LUFA. This -PID is used in LUFA's USBtoSerial project, which forms the basis for -arduino-usbserial. According to the LUFA documentation, this VID/PID -combination is: - - "For use in testing of LUFA powered devices during development only, - by non-commercial entities. All devices must accept collisions on this - VID/PID range (from other in-development LUFA devices) to be resolved - by using a unique release number in the Device Descriptor. No devices - using this VID/PID combination may be released to the general public." - -The production version of the arduino-usbserial firmware uses the -Arduino VID. This is only for use with official Arduino hardware and -should not be used on other products.
