Well not the answer I was looking for, but this is what I got when attaching the OTG port of a new cubieboard2 (NOT in FEL mode) to a USB port on >an AMD64 / FreeBSD system. Since the messages all seem to refer to removable storage devices attached to the same bus on which the storage medium itself doesn't seem to be present, resulting in the devices being reported as not ready, the only thing I could imagine were the SD card slot (I believe using a converter it is possible to connect that to a USB port as well) and the two other (i.e. non OTG) USB ports.

Looking into this a bit further is the difference maybe the result of a different way of enumerating devices on Linux then on FreeBSD?

If not, what conclusion should I draw from this?
