If yes, how much can it support/expect the transfer rate(throughput) in maximum?

Kaka,

Yes, the throughput will be depending on 1) the performance of the other end of the cable - host or device, and 2) the OS, which has different USB sw stack.

Hi Bin,

Thank you for your response.

As your previous post, you said that "depending on the use case, the throughput could be around 100~200Mbps with the SDK kernel."

Have you ever tested this? If yes, would you please teach the test environment?

Best regards

Yes, I tested some use cases, such as AM335x USB in host mode connecting to a MSC, Webcam, or USB2Ethernet device, and AM335x USB in device mode as a MSC or Ethernet device connecting to a Linux or Windows host.
