We can't halt the host controller immediately when first HCD is removed as it will cause problems if we have devices attached to the second (primary) HCD, like a keyboard. We've been carrying this in our Linux-as-a-bootloader environment for a little while now. The machines all have the same TI TUSB73x0 part, and when we kexec the devices don't come back until a system power cycle.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. 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.
