commitfb5ee84ea7upstream. Some non-compliant high-speed USB devices have bulk endpoints with a 1024-byte maxpacket size. Although such endpoints don't work with xHCI host controllers, they do work with EHCI controllers. We used to accept these invalid sizes (with a warning), but we no longer do because of an unintentional change introduced by commitaed9d65ac3("USB: validate wMaxPacketValue entries in endpoint descriptors"). This patch restores the old behavior, so that people with these peculiar devices can use them without patching their kernels by hand.

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.
