Patch Set 2: (1 comment) I've reduced this to the single path that is expected to work and tried to minimize changes. If somebody figures out more working combinations, I'd be happy to merged them. But I'll probably not work on this myself (unless my employment comes into play). Even the Dediprog specification I got my hands on is worth less than a USB trace.
