The usb_f_printer gadget driver uses a default q_len value of *0* which prevents any IO from occurring. Moreover, once the driver is instantiated it is impossible to change the q_len value. The following patch uses a default q_len value of 10 which matches the legacy g_printer gadget driver. This minimizes the possibility that you end up with a non-working printer gadget. It is still possible to set the q_len to a different value using the configfs path of the same name.

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.
