Is there a technique to decode vendor unique USB commands using a beagle 480 (totalphase) to make the trace more easily readable? When I look at the "info" tab now, I see the report ID and "undefined". I know how to decode these, but it would be nice if they were decoded here, automatically.
thx for any help/suggestions that you can offer
-
Unfortunately, the number of vendors using vendor-defined report IDs and the frequent absence of documentation on them makes it difficult/impossible for analyzer vendors to decode the reports.
-
thx Jan - I left out an important part, i.e., in this case, I work for the vendor so I can decode it manually but I was wondering if there is some way to get that info into the trace. We have a lot of vendor unique usages!
-
Ah, that's different...it would depend on whether the tool vendor opens up their software to allow that.
Ellisys has a software kit that supports it:

I don't know about Total Phase, but they should be able to tell you.

Ellisys says, "Decoding of proprietary protocols", which is exactly what I'm looking for - I'll check that out and also see what totalphase has to say too. Thx!
