Justin Hammond 86da4d11ea drivers/usbhost: Correct the style of usbhost_hub.c.
nxstyle reports fourteen errors in this file.  The switch in
usbhost_hub_configdesc() puts its case labels level with the brace that
opens the switch rather than one step further in, and a declaration is
followed straight away by a statement.

CI checks every file a patch touches rather than only the lines it
changes, so these have to go before anything else in this file can be
altered.

Whitespace, three comments rewrapped to stay inside the line limit
after the extra indent, and one blank line.  No code changes: git diff
-w shows only the comments.

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).

For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.

Getting Started

First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.

Documentation

You can find the current NuttX documentation on the Documentation Page.

Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.

The old NuttX documentation is still available in the Apache wiki.

Supported Boards

NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.

Contributing

If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
