This allows them to define a maximum access time. In contrast, Ethernet devices get less bandwidth as devices are added to the same node, therefore, maximum latency times cannot be guaranteed. This is particularly a problem for highly loaded nodes, such as those carrying image data. Additionally, Ethernet is more difficult than USB to implement at the board level.

EtherCAT might be the next logical solution as more transducers are controlled by a single PC or a device based on PC architecture. Cool blogs, keep them coming :) Yes, USB has certainly helped a lot to realize complex PC based automation projects.
