As I mentioned in my previous post I discovered a bug in the ddserver code that would result in a broken USB and wireless connection.
With the V0.2-13 version I fixed that error.
I provided the firmware images (factory, sysupgrade) in the downloads section as a new method for updating the ddserver package.
I suggest that everyone who already has the latest MR3040 ddserver OpenWrt firmware to use the new package updater as it is faster and less error prone.
