Hello
I want to use the USB_OTG port on i.MX7 as Host/Device. The USB_OTG specification says if I want 

to use a USB_OTG Interface as host one need to ground the ID Pin <10 Ohms. Is there any reason to 

ground it with a pulldown of 10k like its done on the i.MX7Sabre EVB on USB_OTG2?

OTG2 is there used as host only.

 

Can one say if its allowed to just Pull the ID Pin externally high, instead of left it floating, when I want to use OTG as USB device?
