   We designed the USB OTG of IMX 286 as USB device port.The usb cable will be connected with USB Host when the PCB board power on.We want to do resetting usb device when booting up.This effect of the resetting process we expected is as usb cable plug out and plug in.

  My question is how to do it? I try to Power on/Power down the USB PHY(32.3.1 USB PHY Power-Down Register (USBPHY_PWDn)),however,it's failed.
