well I think there is a lot of confusion here!

The mainline tree dabusb driver code is outdated: it supports only the
prototype of the device when it was in development 10 years ago. The
out-of-tree dabusb driver code is required for controlling the
commercial device sold by Terratec (DRBox1).

I still haven't checked whether the released dabusb firmware source
code corresponds to the firmware image that is currently requested. I
think it is **possible** (although improbable) that the firmware might
have been kept the same as the one used 10 years ago. I am trying to
build the firmware now from source in order to compare the results to
the currently requested binary file.

I have already done this kind of work with the keyspan/xircom firmware
source codes. More about this topic in another email thread to avoid
