USB IDs

Three IDs are available for configuration by the user :

„Vendor ID

„Product ID

„Release Number ID

According to USB Organization: “Vendor ID (VID) is owned by the vendor company and is assigned and maintained by the USB-IF only. E-mail admin@usb.org for more information on USB-IF membership and obtaining a VID”.

Atmel allows limited usage of its VID (03EBh) during product development phase. Customer use of the Atmel Vendor ID is not guaranteed by Atmel. The customer must use its own Vendor ID for production.

Note: Refer to SYSTEM_CONFIG command.

The following strings are printed during USB drivers installation and during disk drivers
