i.MX 8M Mini: USBx_VBUS pin functions when used as a USB host

[Y_Kanda]

Hello,

I am working on a board design with i.MX 8M Mini and want to use it as a fixed USB host.
In this case, what function does the USBx_VBUS pin have?
I want to understand the USBx_VBUS pin when using a USB host and design it appropriately.

USB_VBUS1 pin is used to detect USB device, it can't be used 5V directly. The usage is  :  (1) 5V-->Series 1k -- series 30k--->USB_VBUS1
