Reading bEndpointAddress the spec tells is that: b7 is direction, which must be ignored b6:4 are reserved which are to be set to zero b3:0 are the endpoint address In order to be backwards compatible with possible future versions of USB we have to be ready with devices using those bits. That means that we also have to ignore them like we do with the direction bit. In consequence the only illegal address you can encoding in four bits is endpoint zero, for which no descriptor must exist. Hence the check for exceeding the upper limit on endpoint addresses is removed.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the reStructuredText markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
