Glenn Grant has blogged recently about going down the USB Reverse Engineering rabbit hole. He does a deep dive into the software and hardware used to reverse engineer, do protocol analysis, do hardware hacking, and do what whatever else would be involved in implementing custom drivers for arbitrary hardware. USB is a ubquitous, industry standard for cables, connectors, and their supporting protocols with a surprising amount of computing power running internally on chips inside the USB devices themselves.

... is that the software protocols are fiendishly complex.
The hardware protocol in my understanding is straighforward but I haven't studied it much.
The xHCI spec is a register-level standard that enables plug-compatible USB host bus adapters with just one driver. That spec is over 300 pages. The guy I share my office with at my current client is listed in the credits.
Quite likely I'll purchase a USB 3.0 protocol analyzer, but I'll have to save up for a while as a used one is four grand.
While the latest spec is 3.1 I cannot hope to buy a sniffer for it.
