The ISO packet throughput can be increased by increasing the buffer size, burst size, buffer length, Iso packets number. For more details, please refer section 6 (Isochronous Transfers) in the below application note:

Thank you for your help!!! The throughput has really increased!
But now I have another issue.
I need to connect to USB hub several ISOC devices to reach backpressure.
But when I connect additional device (with the same image) the second device is working much slower and I starting get a lot of failures.
I’m just studying USB and I guess that problem could be that both devices are using the same ports. Is that correct?
How can I get several devices working with the high throughput?
