Hi,
I'll save that for when I get back to it :) Here's how I packaged the g_cdc (ethernet+cdc-acm together) https://github.com/karlp/openwrt/commit/40c791f5bfbbf6825087db2fc87f88a73f7fa94c I've got a few other patches for gadgetmode, but some of it needs a bitmore testing yet, so I've not proposed it to openwrt yet.
