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. \ No newline at end of file diff --git a/firmwares/arduino-usbserial/Descriptors.c b/firmwares/arduino-usbserial/Descriptors.c index 04bdf98..e4ad956 100755 --- a/firmwares/arduino-usbserial/Descriptors.c +++ b/firmwares/arduino-usbserial/Descriptors.c @@ -67,7 +67,7 @@ USB_Descriptor_Device_t PROGMEM DeviceDescriptor = .VendorID = 0x03EB, // Atmel - .ProductID = 0x2018, // PID_MegaCDC + .ProductID = 0x204B, // LUFA USB to Serial Demo Application .ReleaseNumber = 0x0000, .ManufacturerStrIndex = 0x01, -- cgit v1.2.3-18-g5258
