| :name: Legacy USB Mass Storage |
| :relevant-api: _usb_device_core_api |
| |
| Expose board's RAM as a USB disk using USB Mass Storage driver. |
| |
| Overview |
| ******** |
| |
| This sample app demonstrates use of a USB Mass Storage driver by the Zephyr |
| project. This very simple driver enumerates a board with RAM disk into an USB |
| disk. This sample can be found under |
| :zephyr_file:`samples/subsys/usb/legacy/mass` in the Zephyr project tree. |
| |
| .. note:: |
| This samples demonstrate deprecated :ref:`usb_device_stack`. |
| |
| Requirements |
| ************ |
| |
| This project requires a USB device driver, and either 96KiB of RAM or a FLASH device. |
