emUSB-Host

The emUSB-Host software complies with the USB standard specifications as set by the USB Implementors Forum. It supports all transfer modes (control, bulk, interrupt, isochronous) at all speeds. USB pipe management and extended error recovery mechanisms required for reliable operation are implemented internally. Sophisticated test procedures ensure the reliability and quality of the USB host software. emUSB-Host's modular design enables applications to either access the USB host programming interface directly or to use APIs made available via by class drivers. emUSB-Host can handle multiple devices as well as hubs simultaneously and fully supports hot plugging of devices and hubs. The programming interface supports dynamic device enumeration and identification.

emUSB-Host components

SEGGER's USB host stack designed to work on any embedded system with a USB host controller. Bulk communication along with all other transfer modes is supported. All commonly used standard device classes are supported. USB trees with multiple hubs are supported as well.

emUSB-Host consists of three layers. These layers are a driver for hardware access, the emUSB-Host core, and at least one USB protocol layer.

SEGGER recommends to purchase emUSB-Host as a complete package by selecting the emUSB-Host PRO package. It includes support for the most common use cases, such as handling human interface devices for user interaction, handling USB sticks to export and import data, printer support and serial communication support. The following table shows, which modules are part of the PRO package and which are optionally available.

emUSB-Host drivers?

emUSB-Host does not contain any hardware dependencies. These are encapsulated through a hardware abstraction layer, called a driver. In order to manage the number of required drivers, emUSB-Host has a flexible driver concept, that supports almost all host controllers in the market.
