Our customer has question below.
When using OTG port of USB Function in i.MX6DL , there is a problem that the cutoff measure when disconnect USB Host device is slow.
When the source cord was confirmed, it was the following cord.
It's defined as 155ms-200ms on Spec in USB OTG defined by usb.org, but their system is 500ms setting.
I think there is no problem even in the 155ms according to the Spec. Or it will become a problem because it is set to 500ms in the relationship of the electrical characteristics of i.MX6.
/* B-Idle to A-Disconnect */
#define TA_BIDL_ADIS (500) /* TA_BIDL_ADIS: section 5.2.1
* 155ms ~ 200 ms (but not enough)
