Segger OS layer for emUSB-Host (9.60.00)

A USB Host stack for embedded systems, providing full compliance with the USB specification and support for all transfer modes: control, bulk, interrupt, and isochronous. It enables simultaneous operation of multiple USB devices and hubs, dynamic enumeration, and full hot-plugging support. The suite covers a broad set of device classes, including communication, networking, audio, HID, mass storage, MTP, CCID, and USB-UART converters. Its modular architecture and RTOS integration allow for flexible adaptation to professional industrial and embedded applications. Segger emUSB-Host PRO (9.55.04)

A basic USB Host stack for embedded systems, supporting USB peripherals, including the MSD and HID classes. It provides full host functionality, hub support, all transfer modes (control, bulk, interrupt, isochronous), dynamic enumeration, and hot-plugging. The stack offers advanced pipeline management and error recovery mechanisms, ensuring high operational reliability. Its modular architecture with a hardware driver layer allows for easy integration with a variety of hardware platforms. Segger emUSB-Host BASE (9.30.00)

An extension of the USB Host stack that supports USB Communications Device Class (USB CDC)-compliant devices, acting as a virtual serial COM port. It enables communication with GSM, 3G, and LTE modems, cable modems, and devices such as POS terminals that use CDC for data transmission and configuration. The module allows sending and receiving data, configuring transmission parameters, and simultaneously managing multiple devices, generating connection status notifications. Low RAM and ROM requirements and available sample code facilitate integration in embedded systems. Segger emUSB-Host CDC Class (9.35.02)

An extension of the USB Host stack enabling communication with USB devices using non-standard, vendor-specific protocols. It allows the integration of specialized peripherals into embedded systems without the need to create a proprietary low-level USB layer. The module supports all transfer types: bulk, interrupt, control, and isochronous, offering high performance with low RAM and ROM footprint. A simple API and support for synchronous and asynchronous operations facilitate the implementation of flexible communication in demanding embedded designs. Segger emUSB-Host Vendor (9.35.04)

A USB Host stack extension enabling support for CCID-compliant smart card readers in embedded systems. It allows for easy enumeration and communication with contact, contactless (NFC), and RFID card readers without the need to develop custom low-level drivers. The module provides a simple API for sending APDU commands and generates notifications of reader connection and card insertion. Low RAM and ROM requirements make the solution ideal for access control, authentication, and IoT applications. Segger emUSB-Host CCID (9.35.06)
