Available on iOS/iPadOS >= 17, where this new interface is used by
developer tools using the new RemoteXPC protocol.
This private interface lacks a status endpoint, presumably because there
isn't a physical cable that can be unplugged, nor any speed changes to
be notified about.
Note that NCM interfaces are not exposed until a mode switch is
requested, which macOS does automatically.
The mode switch can be performed like this:
uint8_t status;
libusb_control_transfer(device_handle,
LIBUSB_RECIPIENT_DEVICE | LIBUSB_REQUEST_TYPE_VENDOR |
LIBUSB_ENDPOINT_IN,
82, /* bRequest */
0, /* wValue */
3, /* wIndex */
&status,
sizeof(status),
0);
Newer versions of usbmuxd do this automatically.

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.
