emUSB-Device

emUSB-Device enables easy integration of USB functionality into an embedded system. Multiple standard classes are provided that allow embedded systems to behave as standard USB devices and communicate with any host like Windows, Linux and Mac systems. Examples are mass storage device, keyboard, mouse, printer, speaker, modem, RS232 serial adapter or network adapter. Additionally proprietary protocols may be implemented using the BULK class provided by emUSB-Device. Multiple classes may be combined in any way to form a Composite Device with multiple interfaces that can be used simultaneously.

Target emUSB-Device components

emUSB-Device Consists of Three Layers. These layers are a driver for hardware access, the emUSB-Device core, and at least one USB class driver or the bulk communication component. USB class drivers (MSD, CDC, HID, MTP, RNDIS, IP, MIDI), Bulk communication component and VirtualMSD component can be combined in any way to suit the requirements of any target USB-Device.

USB class drivers and hardware drivers are separate packages, which can be combined and ordered individually to suit the requirements of any project. SEGGER recommends to purchase emUSB-Device as a complete package by selecting the emUSB-Device PRO package. It includes support for the most common use cases, such as human interface devices for user interaction, file storage and transfer and serial communication support. The following table shows, which modules are part of the PRO package and which are optionally available.
