Hi Megha,

The AM62L USB module compliant with the USB Spec, it shouldn't have issue in detecting USB hubs.

Do you run Linux on AM62L? If so, did you set dr_mode to "host" in devicetree for the USB port which connects the hub?

In your schematics the hub upstream port, where do the USB supper-speed signals (USB2_TXN/P and USB2_RXN/P) go to?
