Hello Kai,

That's correct, you only have to increase the AC caps to 0.5uF (C6, C7, C8, C9, C12, C13). This is because these capacitors will end-up in series with the AC coupling capacitors on the Device and Host. (It is the same design we used on the HD3SS3220 DFP Dongle Evaluation Module).

Regards,

Diego.
