Hi all
I want to confirm a USB behavior, when I use USB as Host
When D+/D- goes High before initialization, can I detect Attach event ?
I read those following descriptions but there are no explanations.
"65.4.3.1 Host Controller Initialization"

Hi Igor
Thank you for your reply.
I understood like this↓. Is it correct ?
Since the detection of attach event before the initialization has been defined by the standard so i.MX6 also can be detected.

Hi ko-hey
in general attach event can be detected before
full usb controller initialization, please look at
sect.66.2.4.5 USB Plugged-In Detector IMX6DQRM
Description for attach event can be found
in sect.7.1.7.3 Connect and Disconnect Signaling usb 2.0
specification.
Best regards
igor

I apologize for any confusion.
I mean following sentence.
「Since the detection of attach event before the initialization has been defined by the standard so i.MX6 also can be detected.」
