    Hi Lawrence,

    The TUSB1044 could work in the block diagram you've shown. The SBU lines do not need to connect through the TUSB1044, but you should connect AUX so we can snoop the aux lines.

    Does the customer's host have an integrated AUX/SBU MUX? I'm confused why they want to bypass the TUSB1044 AUX/SBU MUX in this application. The purpose of this MUX is to connect the AUXp/n lines correctly in both the normal and flip type-C orientations.

    Best,

    Shane
