Hi community,


Our customer have a question about i.MX6UL USB.
They want to confirm what function should be assing to i.MX6UL pad to use i.MX6UL as USB device only.
Especially, whether OC and ID pin is needed or not.
I think both function pins are not needed with the following reason.
For OC pin:
Over current detection is the function for USB host, so OC pin is not needed when use i.MX6UL as device.

For ID pin:
If ID is not assigned to any pins by IOMUX, ID will be floating.
In this case, i.MX6UL behave as USB device.
Is my understanding correct?
