Sorry, but "Type B" is even more confusing here. Type B refers to the
Standard-B USB connector, so _not_ the micro connector family. You can
check the connector definitions from the latest USB 3.2 specification.
The standard-b definition goes something like this:
"The standard _Type-B_ connector defined by the USB x specification."
Note that all the five supported connectors are listed in ch5
"Mechanical":
Standard-A
Standard-B
Micro-B
Micro-AB
Type-C
So what was the problem with names that refer to the micro connector
family, for example "micro-ab" or "micro-b"?
