Hi all,
Playing with USB ethernet gadget on IGEP boards with mainline kernel
(Linux 3.0.0-rc7) I observed one strange behavior. The ethernet gadget
works with one board with OMAP3530 but it doesn't with another one
with DM3730. The log looks like this:
root@igep00x0:~# modprobe g_ether

With DM3730 I can't ping the other side (the same configuration with
OMAP3530 works without problems). Any clue on this ?
Cheers,
Enric
