I haven't tested USB myself, as I'm not using second stage barebox after
u-boot and there's still things missing for USB to work on first stage.
Currently only SDMMMC is fully supported.
Are you testing exactly this commit? If so you might need to apply
431d8a247dfa63f817cda137a81dbb2244d413dc "arm: properly init alignment
trap bit", as USB might trigger an unaligned access.

You'll notice that a newer barebox won't build images for AC100 that are
suitable to burn into a boot media, because there are no BCTs publicly
available for this device. The resulting AC100 image is only useful for
starting with TegraRCM.
