DM816x : USB host mode : VBUS input may be disconnected ?

Other Parts Discussed in Thread: AM1705

Hello,

My system is configured has (usb) host and cannot detect when a device is plugged in. I'm suspecting that VDD_USB0_VBUS input is disconnected.Note that the same firmware runs on a similar design and USB functions correctly on that variant.

If it's the case, then would this prevent the USB controller or PHY from operating ? If so, can the controller me made to 'ignore' VBUS input ?
