Well, the attached usb snoop you last sent is unfortunately even worse
and totally unusable, only a few bytes exchanged are shown here.

I'm very skeptical if we can come to some success using the current
ImageClass protocol, I'm afraid a rewrite of this new protocol is
necessary. With understanding of new messages, how they are formated and
of the data they content, this requires having access to a real device
for testing. 

But first, if you could produce this alternate usb snoop, this may
help,
