Yoshiki Ochi

Hi team,

Consideirng two ports of USB 2.0 data communication, does CDP handshake process supported by the HUB device? Image is shown in following figure.

Or do we need CDP handshake supported processor connected to HUB?

HI Ochi:

host don't need to support CDP. Hub itself can support CDP handshake when BATENx is pulled up to 3.3v.

Hi Brian

Thank you so much. We understood the Hub device itself has handshake function.
