HX3PD is USB3.1 Gen2 Hub. If the bandwidth is gate by the Gen1 hub, you could try this one. Otherwise, you should find out the root cause of short of bandwidth at first.
Thanks for your reply. The Hubs I've been testing are Gen2, not Gen1.
The cause of the bandwidth issue on these hubs is that they do not use the "Store and Forward" architecture of USB3.1 Gen2 to aggregate the traffic from multiple SS devices.
I would like to know if the HX3PD is capable of running multiple SS devices and utilising the full 10 Gbps upstream bandwidth. The datasheet indicates that it has a "router/aggreater engine", and the Store and Forward architecture is mentioned.
Is there any data to indicate that two SS devices, such as an FX3, can simultaneously run at their full SS rate when they are connected to the HX3PD hub?
1. Yes. HX3PD is capable of running multiple SS devices and utilising the full 10 Gbps upstream bandwidth.
2. The data is TID of USB-IF which is guarantee the specification of USB-IF.
