Title: A10 USB OTG ID pin
Post by: scott-alex on August 26, 2014, 01:40:17 pm
The USB OTG ID pin on the A10 board is pulled high via R42. However the specification of USB OTG states that the ID pin should either be left floating for a device or grounded for a host.

Can you please explain why this is pulled high on the board?

Thanks
