CSUSBD
CSUSBD Real-time USB device software stack designed for embedded systems that allows the creation of products that interoperate with standard USB devices.
Key Features
Thanks to a hardware abstraction layer, you can easily port Cs/USB software to any new USB device by simply modifying existing hardware access routines.
- Support for High Speed (480 Mbit/s) and Full Speed (12 Mbit/s) devices
- Compliant with USB 2.0 specification
- Easy-to-use API
- Extensive test cases and test harness to verify stack integration
- Support for composite (multifunction) devices
- Support for multiple USB device configurations
- Power saving functionalities such as device suspend and resume
- Support for Audio, CDC-ACM, CDC-EEM, HID, MSC, PHDC, and Vendor classes
- Support from Microsoft OS Descriptors for USB devices (which simplifies installation of vendor-specific drivers on Windows OS)
USB Device Classes
| Class | Example USB Devices |
|---|---|
| Audio (Available for devices using the Synopsys_OTG_HS driver) | Support audio devices such as speakers, microphones, headset, etc. Extended audio functions (such as adaptive audio correction) and controls (volume, mute, treble, bass, etc.) |
| Communications Device Class Abstract Control Model (CDC-ACM) | Emulation of a virtual serial port on the host PC The host PC can communicate with the device using a serial terminal or native serial communication APIs |
| Communications Device Class Ethernet Emulation Model (CDC-EEM) | Ethernet networking over USB The Cs/NET stack is used for network communication and any of its applications can be used |
| Human Interface Device Class (HID) | Support for devices such as mice and keyboards |
| Mass Storage Class (MSC) | Support for storage media from the host PC Offers advanced features such as interoperability with Cs/FS file system module |
| Personal Healthcare Device Class (PHDC) (Available for devices using Cs/OS2) | Allows to build USB devices that are meant to be used to monitor and improve personal healthcare USB Device Class Definition for Personal Healthcare Devices |
| Vendor Class | The vendor class allows you to create any device that cannot fall into a standard class for which a standard has been set by the USB implementers forum. It allows you to perform raw bulk and interrupt communications with the host. Cs/USBD offers a framework to help create host applications (Windows OS only) that communicate with these devices |

USB Command Verifier (USBCV) is used to validate the compliance of the stack with the USB Specification. USBCV is the official compliance test tool that evaluates High, Full, and Low-speed USB devices for conformance. This tool is provided by the USB Implementers Forum (USB-IF).
USBCV offers a test suite to validate the compliance of a device with Chapter 9 of the USB specification Revision 2.0 (enumeration process). It also offers a test suite for several classes.
| Layer | USBCV Test Suite |
|---|---|
| Core | Chapter 9 tests |
| Human Interface Device class | HID tests |
| Mass Storage Class | MSC tests |
| Device Controller Driver | Chapter 9, HID, MSC, and PHDC tests |
Commercial License
All Cesium RTOS components are commercially licensed. All commercial licenses are a one-time purchase that are perpetual for the life of your product and royalty-free. We use the same simple licensing model as did Micrium, based on your end-product's deployment, for establishing the commercial license costs. The following types of licenses are available for purchase:
Single Product License
A Single Product License allows you to embed a Cesium RTOS software component into one customer end-product. There is no limitation on the number of end-customer products deployed. This license is specific to the processor used and the specific name and model of the customer end-product.
Product Line License for Single CPU
A Product Line License for a Single CPU allows you to embed a Cesium RTOS software component into any number of customer end-products within a given product family. You may use only a single and specific processor type within the product family. You may deploy an unlimited number of these customer end-products within the product family.
Product Line License
A Product Line License allows you to embed a Cesium RTOS software component into any number of customer end-products within a given product family, and to deploy an unlimited number of these customer end-products within the product family.
CPU (Platform) License
A CPU-Type License allows you to embed a Cesium RTOS software component into any number of customer end-products using a single and specific processor type. You may deploy an unlimited number of these customer end-products.
Site License
A Site License allows you to embed a Cesium RTOS software component into any number of customer end-products that use any CPU, as long as the products are designed at a single site. There are no restrictions on design or quantity.
