Hi community,


Our partner have a question about i.MX6DQ USB OTG.

They want to use USB role swqpping with HNP.

They will use i.MX6DQ USB OTG as host normally (OTG A-device), and change its role when Host request flag comes from USB B-device.

In this case, how should they connect USB_OTG_ID pin?

Tied to GND? or control its logic high or low by GPIO?
