Coral SOM host mode

(1/1)

maxpayne:
I am designing a hardware based on the Coral SOM and the dev board schematic. Here is the datasheet of the SOM -
https://raw.githubusercontent.com/SeeedDocument/Bazaar_Document/master/Coral-SoM-datasheet.pdf

On page 20, there is the USB pin-outs. I don't need the OTG function and want to run both the USB ports as host. There is no documentation in this respect in the datasheet.

    1. For host mode, how should I configure the 4 pins, USB1_VBUS, USB2_VBUS, USB1_ID and USB2_ID ?
    2. Should I connect the ID pins to GND ?
    3. Whats the function of VBUS detect pins ? Does this pin state matters in the host mode ?

maxpayne:
Whats the harm in asking here ? please explain ...

maxpayne:
Google is very slow in support. For Coral, they actually redirects any queries to Asus China, probably OEM for the Coral SOM. Which takes a significant time and hard to understand their reply with their Chinese English.
