Here are the results I found:
Harmony:
Tegra USB3 -> SMSC9514 hub: NOT affected
(Unplugging LAN cable, or disabling SMSC9514 LAN driver doesn't change this)
Seaboard (springbank; clamshell):
Tegra USB1 -> no hub: Affected
Seaboard (seaboard non-clamshell):
Tegra USB1 -> no hub: Affected
Tegra USB3 -> no hub: Affected
TrimSlice:
Tegra USB3 -> unknown hub: Affected
This implies there's something different about Harmony.
Is the USB hub a clue? Seaboard doesn't have one, and although I don't
know what model TrimSlice uses, I assume it's different since I know
TrimSlice's Ethernet is not the same as Harmony's.
I don't see anything in board-harmony.c vs. board-seaboard.c that'd affect
anything USB-related.
Perhaps there's some kind of bootloader or BCT difference. However, my
Harmony and both Seaboards both use (a very old) U-Boot and BCT from
ChromeOS, so I don't imagine there's actually much difference there.
