mx53loco: Turn on VUSB regulator
On the mx53loco board with mc34708 PMIC it is necessary to turn on VUSB regulator so that the mx53 USBH1 PHY receives the 3.3V voltage. Tested by inserting a USB pen drive in the upper USB slot (USBH1) and then issued the commands: usb start usb info ,which correctly detected and printed the USB pen drive information.
