Last week I booted the NetBSD 9 image for ODROID-XU3/XU4 off armbsd.org on
a HC1.  That detected the USB to SATA bridge just fine.  I don't remember
if I tried to transfer data.
I also booted the NetBSD -current image off armbsd.org and that did not
detect the USB to SATA bridge.  There was some USB related error in the
kernel messages that I didn't bother to write down because it is easy to

Obviously there's some regression since NetBSD 9.

I noticed that the Armbian uboot loads a different DTB file on the
hc1/hc2.  Maybe that would make a difference.  If not, then there is some
kernel debugging to be done.

I haven't looked at what exactly would be necessary to use the different
DTB.  So I can't give you concrete advice.
