  • Apparatus and method for initializing a universal serial bus device
    Patent number: 6353866
    Abstract: A method and apparatus for dynamically assigning and enabling a unique functional address for a Universal Serial Bus device. A host assigns the unique functional address during a control transaction. The Universal Serial Bus device disables the default address and enables the unique functional address during a status stage of the control transaction to avoid an error window.
    Type: Grant

  • Apparatus and method for handling universal serial bus control transfers
    Patent number: 6205501
    Abstract: A method and apparatus for performing a control transfer on a Universal Serial Bus (USB) device. A USB device includes a memory space for reading and writing data transmitted over a USB network. The memory space is shared between a plurality of endpoints. A host initiates a control transfer by transmitting a SETUP token to a first endpoint. The endpoint must accept the SETUP token. If the first endpoint does not expect the SETUP token, or if another endpoint is active, the device stores the token until a buffer is allocated and the first endpoint is made active.

  • Apparatus and method for transmitting and receiving data into and out of a universal serial bus device
    Patent number: 6122676
    Abstract: A method and apparatus for dynamically configuring a USB device. The USB device includes a plurality of mappings for relating a received token to an endpoint pipe. The mappings are configured at initialization, and are dynamically selected during operation of a USB network.
