STUSB4700QTR powersource and datasink

[Erwin_N]

I have the following situation:

I have a custom PCB with a 4 port HUB ic on it (TUSB8041IRGCR). The UFP of the hub is connected to  my phone and there are 4 DFP.
My phone negotiates with the PD controller via CC lines about what voltage it wants when phone is connected. The datalines of the usb port go to the hub. The thing is that the phone does not see the hub. If i completely ignore the USB PD negotiation and connect the UFP to my PC, the PC sees the hub.


is there some sort of setting i have to set  in STUSB4700QTR to let my phone know that it sinks power but sources data to the hub? I have no option to program the STUSB4700QTR

Hi , STUSB4700QTR is not able to act as DRD (dual Role Data ) , it does not support any Data role swap messages , so even if you controler is device capable le link will stay host

Do you have a suggestion on how to fix this issue?

Apologize, the STUSB4700QTR can not provide properly support Data swap messages 

without conflicting internal states machines
