I actually tried uboot-sunxi repository (and then checked out on merge commit in master for this repository) and it is working as expected: I get Ethernet over USB. I tested with master (43d3fb5c0609a76409e7859a2a5800670c7b5bd2) and I first get a reset of the board when starting USB (before I can enter U-Boot command line) and then after the reboot, U-Boot hangs on starting USB (still before the command line). I did a git bisect on master and it returned this commit: http://git.denx.de/?p=u-boot.git;a=commit;h=3f9f8a5b83f8aec40c9f4ee496046a695e333c45 Tell me if I can help in any way.
