Check the values of the USBx_GHWPARAMS3 and USBx_DCFG registers.

The LS1046a USB register after reset are configured for SuperSpeed mode.

Have a great day,

Check your board using attached files. These files contains documentation and schematic for the LS1043ARDB USB and layout guidelines for high-speed interfaces (USB, PCI).

Have a great day,
