USB 3.0 Specification Release

A description of the Universal Serial Bus [USB] has resided on the site for years now. That page dealt with revisions 1 and revisions 2.0. However the specification changes within revision 3.0 are so different a new page has been created; Super Speed USB.

Revision 2.0 of the USB specification operated up to 480Mbps, while revision 3.0 of the standard can operate up to 4.8Gbps a 10x increase in the operational data rate. The cable and connectors have also changed by adding two additional twisted wire pairs.

The new page is still a copy of the original USB but over the next few days the 2.0 data will be replaced by the 3.0 information. Also added a new page to hold the new 3.0 USB Cable diagram, but again it's still a copy of the revision 2.0 cable.

Automotive Buses

A new page was added off the main Automotive Bus description page to cover the Mazda Engine Control System. I get the impression that the Mazda Engine Control bus was used up until the mid 1990's when it was replaced by the Electronic Engine Control [EEC] interface. The system was used with engines produced by Mazda and with Ford cars that used Mazda engines.

Can't find much data out on the web, so there are only a few words on the topic.
