Abstract: A system for enhancing universal serial bus (USB) applications comprises an upstream processor, a downstream processor and a main controller. The upstream processor accepts standard USB signals from a USB host and independently provides responses required by USB specification within the required time frame. The upstream processor also contains storage for descriptors for a device associated with this upstream processor. The main controller obtains the descriptors by commanding the downstream processor, and passes them to the upstream processor. The downstream processor connectable to USB-compliant devices accepts the USB signals from the USB-compliant devices and provides responses required by USB specification within the required time frame. The main controller interconnects the upstream and downstream processors, and provides timing independence between upstream and downstream timing. The main controller also commands the downstream processor to obtain device descriptors independent of the USB host.

Abstract: A method and system for obtaining consumer preferences over a communication network from consumers. The system searches the product database for products or services based on consumer's search criteria. The system displays the products or services and/or advertisements related to the consumer's search criteria in accordance with the ranking parameter(s) specified by the user. The consumer's preferences, i.e., the search criteria and the ranking parameter(s), are stored in the database for future references, e.g., determine consumer trends, etc.

Abstract: Apparatus and method for converting protocol and code for use with a Human Interface Device (HID)-compliant keyboard device comprises a Universal Serial Bus (USB) interface, non-USB interface and a converter. The USB interface receives standard USB data from an USB host or hub and provides responses required by an USB Specification for the HID-compliant keyboard device. The non-USB interface can receive data coded in American Standard Character Interchange Interface (ASCII) or Unicode. The converter converts the data coded in ASCII or Unicode into code and format in accordance with the USB Specification for the HID-compliant keyboard device.

Abstract: An adapter electronics circuit that converts signals from a pointing device into codes corresponding to keyboard cursor key actuations. In addition to the pointing device signals, the adapter electronics also accepts all key codes generated by the keyboard and passes them on unmodified to the computer. The adapter electronics plugs into the same terminal on the computer where the keyboard is normally connected. In this manner, all normal keyboard functions are available to the user as well as the use of the pointing device through the normal keyboard terminal on the microprocessor. Most commercially available application software accepts the cursor key codes presented to the computer.
