TUSB4041I: attached device detect

Part Number: TUSB4041I

Hi team, 

I have a question on cpdEN - Enable device attach detection -  this is for auto mode. Why is it disabled by default? Shouldn't each attached device to be detected?

In https://e2e.ti.com/support/interface-group/interface/f/interface-forum/559392/detect-connected-devices-on-tusb4041i?tisearch=e2e-sitesearch&keymatch=TUSB4041I%25252525252525252520auto# it is said that the hub does not have a internal register used to detect attached device.

Can you please elaborate? I am confused, if TUSB4041I is able to detect attached devices and what is the purpose of cpdEN?

Thank you.

Kind regards,

Aida
