A few issues with CBoot...patch attached

Hello, @gtj @WayneWWW @Wiser.Kuo @TWarren

Look at the text below and leave a message.

I’m also having trouble booting the Jetson Xavier NX into emmc when I try to boot it into the usb device in the usbtosata interface.

However, I noticed that if I connected the usbstick directly without going through the usb hub, it would boot into the usb device.
In the article below , I think @WayneWWW also confirmed that the usb pendrive boots up.
Continuing the discussion from CBoot with USB Storage issue:

@TWarren know when the USB hub support discussed below will be available?

Thank you.
