There is no MUSB support for sunxi in the mainline kernel yet. Check http://lists.infradead.org/pipermail/linux-arm-kernel/2014-May/253463.html and the Chen-Yu Tsai's wip branch: https://github.com/wens/linux/tree/wip/sunxi-musb I've got a couple of Allwiner tablets a week ago, so MUSB has also become my problem since then (because there is not other USB connectivity).
