Genoa Technology's Universal Serial Bus Protocol Analyzer

Genoa Technology Inc. announced the immediate availability of its USB Protocol Analyzer. The system is composed of two hardware components: a USB Probe that connects to the USB Bus and a USB Data Capture Board with 32MB of memory, allowing the acquisition of 8MB of USB transitions. The analyzer will detect and report nearly 200 different error types, unlike other analyzers, which report fewer than 10 error types. Users may set the display so that various colors will represent different error types, making it easy to recognize and identify problems.

The USB Protocol Analyzer identifies protocol problems at the data layer, the transaction layer and the event layer. Any layer can be displayed and the time correlations between layers preserved, making it easy to see relationships when debugging. External triggers allow data to be recorded when user-defined events occur.

The Transaction Layer Analyzer displays multiple events from a single transaction in a highly readable way. It allows the entire transaction to be analyzed for conformance to the USB 1.0 specification. If a required part of the transaction is missing or outside of timing requirements, the error is detected and described to the user.

The Data Layer Analyzer presents the data from each transaction and sorts it by user-selectable ``pipes.'' Users may then see, all in one place, the data sent from a specific address and endpoint. All layers are linked, so it is easy to move back to the other layers to see the details of the packets used for transport.

The Event Layer Analyzer displays all recorded USB events. Event types can be color coded for easy viewing.

In post-capture analysis, the USB Protocol Analyzer has extensive display filtering options to pinpoint specific protocol problems. Comprehensive time measurements can be made for event traffic to accurately assess performance. The USB Protocol Analyzer includes sample traffic files containing various protocol violations.

The Genoa Technology USB Protocol Analyzer runs in a Windows 95, 98 or NT 4.0 environment, and is available now for $6,750 (U.S. List Price).
