I tested both 5.04 and 5.05 in accessory mode yesterday and everything works OK on my setup. Is this possibly a power supply problem, either having a poor supply or having the trim-pot on the IOIO not fully clockwise? I can imagine how transients on the power line might cause protocol corruption.
And no, I don't currently have a debug build available. It's a good idea!
