TUSB2077A: HUB not visible on the PC, and HUBCFG stays low

Part Number: TUSB2077A

I have used the TUSB2077A in a design, but when testing the prototype, it seems like the chip does not configure properly. The "HUBCFG" pin is low, and I cannot see it on my computer. I am using this as an onboard HUB to collect the USB lines from several other ICs. Port 6 and 7 is not in use, but routed to a connector as spare.

I would like to use default config so I have not connected any EEPROM, also power control and overcurrent is not needed.
