Yes, that file has been there all along. I've confirmed with roebeet that the problem lies in the boot.img file (xoom_ocboot.img) that is used in the OC procedure. I don't know the exact details, but what has to happen is the dev that put together that .img will need to incorporate roebeet's changes into his, so that both USB host AND OC will work together, without affecting wifi. We've contacted that dev and hopefully we'll have it worked out shortly.Did you try pushing the bmc4329.ko file to /system/lib/modules?
