I want to send data throughto an upstream port of a USB hub and read it through all downstream ports of the hub, without connecting anyeach connected to a different device on downstream portsi.e broadcasting USB data. Basically to observe & ensure if data coming through all downstream ports of hub are same or not.
Are there any ways or tools to do this?
I am trying this on USB 2.0 hub and Ubuntu 18.04LTS system.
