emUSB Host
emUSB Host, Segger’s USB host software stack, implements full USB host functionality, including external hub support, and optionally provides device class drivers. It enables developers to easily add USB host functionality to embedded systems.
The software stack complies with the USB v1.1 and USB v2.0 specifications. It supports all transfer modes (control, bulk, interrupt) at low, full and high speed. USB pipe management and extended error recovery mechanisms that are required for reliable operation are implemented internally.
