Yes, you can use a USB 3.0 Gen2 hub as it will give a high bandwidth of 10 Gbps. Since our USB 3.0 Gen1 hub HX3 gives a bandwidth of around 5 Gbps, you can use it as well if you need a maximum bandwidth of 800 Mbps.
Thanks for the quick reply. My applicaiton is 800MBps, not 800Mbps, so I'll need 6.4Gbps minimum to run. That is too fast for Gen1 hub. Do you have a Gen2 hub chipset that I can integrate into a design?
