Someone reported a problem with their TP-Link WN722N (RTL8188EUS): usb 1-1: This Realtek USB WiFi dongle (0x2357:0x010c) is untested! usb 1-1: Please report results to Jes.Sorensen@gmail.com usb 1-1: Fatal - failed to parse EFuse rtl8xxxu: probe of 1-1:1.0 failed with error -22 This error can happen when the first two bytes of the efuse don't have the expected magic value of 0x8129. In a situation like this it could be useful to see the contents of the efuse. Dump the efuse right after reading it, before trying to parse it.

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.
