Currently we don't configure correctly the wake events after unplug of device router. What can happen is that the downstream ports of host router will be configured to wake on: USB4-wake and wake-on-disconnect, but not on wake-on-connect. This may cause the later plugged device not to wake the domain and fail in enumeration. Fix this by clearing downstream port's "USB4 Port is Configured" bit, after unplug of a device router.

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.
