The driver expects at least one bulk-in endpoint when in "wifi-alone" operating mode and two bulk-in endpoints otherwise, and would otherwise fail to to submit the corresponding bulk URB to the default pipe during probe with a somewhat cryptic message: rsi_91x: rsi_rx_urb_submit: Failed in urb submission rsi_91x: rsi_probe: Failed in probe...Exiting RSI-USB WLAN: probe of 2-2.4:1.0 failed with error -8 The current endpoint sanity check looks broken and would only bail out early if there was no bulk-in endpoint but at least one bulk-out endpoint. Tighten this check to always require at least one bulk-in and one bulk-out endpoint, and add the missing sanity check for a Bluetooth bulk-in endpoint when in a BT operating mode. Also make sure to log an informative error message when the expected endpoints are missing. Signed-off-by: Johan Hovold <johan@kernel.org> Signed-off-by: Kalle Valo <kvalo@codeaurora.org>
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.
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.
