  • USB dynamic service switch for dual processor architecture
    Patent number: 7117288
    Abstract: USB bus enumeration and configuration switching in a dual-processor architected device can result in loss of the inter-processor communication link. In order to solve this problem, an apparatus, architecture and method for simplifying the Universal Serial Bus (USB) service enumeration between two processors in a dual-processor architecture device are provided. A USB host (102) is connected to a first processor (201) of the dual-processor device (100) via a USB cable (104). The first processor (201) begins to enumerate services to the connected host (102). When the host sends a set_configuration request (405) to the device (100), the device determines whether the first processor (201) and the second processor (203) have the same configuration sets. The first processor (201) sends a set_configuration request to the second processor (203) to setup the requested services in the second processor.
