HCC’s USB Host stack is a scalable suite that enables an embedded host to control a variety of USB devices including pen-drives, printers, audio devices, joysticks, virtual serial ports and network interfaces. The embedded USB host stack supports EHCI, OHCI, xHCI, and non-standard USB controllers.
USB Host base system
The USB Host base system is the core of HCC’s USB host stack solution. It supports any number of USB host controllers, each of which may have multiple units. Supported host controllers include any combination of Enhanced Host Controller Interface (EHCI), Open Host Controller Interface (OHCI), eXtensible Host Controller Interface (xHCI), and proprietary host controller types. HCC has many host controller implementations and can add new host controllers on request.
The system provides an interface for any number of USB host class drivers to communicate with their corresponding USB device class drivers. The system supports all USB transfer types (control, interrupt, bulk, and isochronous).
