I have two devices A acting as (UFP) and B (UFP or DFP). Device Device A supplies 3.3V to device B on SBU1 and SUB2 pins of USB C 3.1.

I am not using Vbus to supply power to Device B. SuperSpeed pins of USB C 3.1 are not used as superspeed signals but they are just used for transferring signals from B to A.

My question is can I achieve transmission of signals by using Device A as UFP and Device B also as UFP? Basically can I pull down the CC pins of device A and B?

Note: I am using HD3SS460 MUX on Device A

Thank You.
