The production version of the ROCK 4D appears to sport a AICSEMI AIC8800D80 USB Wi-Fi + BT chipset. This chip does not yet have a mainline driver. Add the necessary rfkill node and wifi regulator node to at least make it show up in lsusb output. The regulator is set as always-on, as like 2 hours deep into debugging why onboard_usb_dev.c wouldn't try enabling the regulator the device needs to actually show up and thus bind to onboard_usb_dev.c, I decided that it's not worth the effort.

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.
