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
============
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.
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.
