Mentor Graphics Corp. has introduced at the 2003 Embedded Systems Conference a USB software stack specifically designed for its Inventra dual role USB OTG controller. The Inventra OTG controller supports both host and function capabilities and is capable of swapping these roles dynamically.

The Inventra USB OTG software stack is designed for environments that require high power efficiency and is capable of coping with the dual-role nature of OTG devices. It detects the connection of a function or a host device and switches automatically to the appropriate mode.

For OTG-to-OTG connections, the stack supports the Host Negotiation Protocol that allows the software to respond to requests for a role change and enables the device to switch seamlessly between modes.

The USB OTG software stack employs a Linux-like API that allows software developers familiar with Linux to build custom drivers for the stack. The stack's class loader enables both static and dynamic linking of drivers.
