Microchip USB5734 hub design

We are designing a board and replaced the RTS5489 USB hub with the USB5734 . The design uses the same usb lanes as per the RTS5489 therefore the dsti files should not require a change as per USB porting guide. The kernel seems to recognise hub (see below) however the hub ports are all inactive and ‘lsusb -v -s’ just hangs. Apart from the dsti files are there any other changes that need to be made?

There should be no change needed. Please contact the hub vendor for help.
