ALFAT OEM Board reference Schemetic - USB connection

File-System Hardware

Hi,

In the reference schematics of ALFAT-OEM board, both ALFAT SOC and HS-PHY are connected to USB-2 (DM2, DP2), isn’t one of them supposed to be connected to USB1 (DM1, DP1) ?

Thanks

Sorry,

Understood the cause.
As per ALFAT Datasheet, Pin 35,36 should be left NC if HS-PHY is used.
