TPS65987EVM: USB 2.0 Pass through

Part Number: TPS65987EVM

Hi there, 

I have a batch of 20 TPS65987EVM boards and 3 of them seem to have issues with the USB 2.0 passthrough paths. All 20 boards have been wired identically. I have pinned out the boards and they all have continuity from type-C connector to expansion connector.

Is there ant known issues with the USB pass through or any work around you can suggest?

    Hi Jordan,

    The TPS65987D does not interfere with the USB2.0 lines. It has a simple sense connection for BC1.2 advertisement and detection. I would double check the firmware configuration on the boards to ensure they all have the correct configuration on them.

    Thank you,
    Eric
