The Boot ROM "defaults" to UART0, this is why you see "CCCCCC's.." over the usart when the eMMC and microSD are blank.. However u-boot can be "easly" programed to change the UART0 to a different UARTx However to change from UART0 to USB0, "you'll" have to do some work.. PS, once you jump from u-boot to app x, the "usb" handoff is complex...
