Great to hear!

This looks like a permission issue, when the alternate interface name
is "UNDEFINED" it is because dfu-util could not read it out. From your
command line below, I would expect the correct name to be "u-boot".

Do you have lsusb in your environment? If lsusb -v can not read out
the name either (listed after iInterface), there is a permission
issue.
