Unstable Device Communication with USB 2.0 High-Speed Hub on Jetson Orin Nano

We are currently utilizing a custom USB hub board equipped with a USB 2.0 high-speed Hub IC on the Jetson Orin Nano developer kit. The version of Jetpack we are using is 5.1.2.

The devices connected to the Hub are as follows:

  • Seeed Studio XIAO SAMD21 on Port 1

  • sparkfun Pro Micro on Port 2

  • FT4232H on Port 3

Upon initiating communication with the FT4232H, we observe the following output in dmesg. This results in an unstable connection to the FT4232H. In the worst-case scenario, the FT4232H device is no longer identifiable by lsusb.

At present, the custom USB Hub board and the Jetson Orin Nano are connected using a standard USB 2.0 cable. We are seeking to understand the cause of this issue.

Hi,
Please check if you can connect to external power supply. See if there is improvement if power is from external source.

And may try to do compliance test with the custom hub. Please check the tuning guide:

We have done compliance test for Orin Nano developer kit. But it may need to be done again since there is a custom hub connected.
