Hi, Team,

Could you let me know the "0x37 AutoNegotiate Sink bit[3] USB Communication Capable" ON/OFF behavior difference between DRP and DFP?

Hi, Aleksey,

I know DRP is Dual Role Port and DFP is Downstream Faicing Port.

There is DFP VBUS output timing difference between register ON and OFF, so I posted the question.

Hi Yone-san,

I would take the definition to be "Can the device enumerate as a (USB) Host or Device". I would assume for a DFP it would be USB Host.

Regards,
Scott
