Unfortunately this is where it often ends unless someone comes around with advanced knowledge on USB commonication.


Those people often sit in labs of technical universities or in the back of radio repair shops. Unfortunately, getting a hold of them is the tricky part.


If you want to spend more enery you could try to contact hardware tinkerers from local Makerspaces if such a thing exists.


I guess the next step would be to obtain a hardware USB debugger like the ones I have referenced. They are around $100 US and come bundled with software that makes capturing reliable.




There are some videos on USB reverse engineering from the Chaos Computer Club in Germany






More often then not, it will be - you - who becomes the expert and masters the art.


Read https://hackernoon.com/usb-reverse-engineering-down-the-rabbit-hole-c4809a5b55c4 and you might just find a pointer to tools or people that might be able to help.
