Ports with _UPC (USB Port Capability) ACPI objects stating they are "not connectable" are not wired to any connector or internal device. They only exist inside the host controller. These ports may not have an ACPI _PLD (Physical Location of Device) object. Rework the code so that _UPC is read even if _PLD does not exist, and make sure the port->connect_type is set to "USB_PORT_NOT_USED" instead of "USB_PORT_CONNECT_TYPE_UNKNOWN". No bugs or known issues are reported due to possibly not parsing _UPC, and thus leaving the port connect type as "unknown" instead of "not used". Nice to have this fixed but no need to add it to stable kernels, or urgency to get it upstream.

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 Restructured Text 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.
