Prohibited cable assemblies
Some cable assemblies are prohibited in the USB specifications and are not recommended as
they may not work in all instances. For example, passive extension cable assembly: a cable that
has a Type-A plug on one end and a Type-A receptacle on the other, or a Type-B plug on one
end and a Type-B receptacle on the other. This allows multiple cable segments to be connected
together, possibly exceeding the maximum permissible cable length.
