How many USB devise cascades can the UPort 400A and UPort 200A support?


Five layers. By definition, the USB-IF should have seven layers of USB device cascading. The host computer and the UPort 400A have each taken one layer already; therefore, five layers remain available for cascading. There are some cases where the host computer design may take more than one layer, so the availability of the cascading layers may vary.
