MCCI develops and licenses USB system software to be embedded into our customers’ consumer-electronics products.

Our USB host stack is the only independent host stack that has been through the stringent SuperSpeed USB certification process. It’s also the only host stack that has been used in mass production on Windows systems.

Our USB class drivers work with any host stack to help connect products to other intelligent systems: for example, PCs, tablets, car electronics, medical equipment, test equipment.

Our USB device stack provides a portable, extensible framework for implementing advanced multi-function USB devices.

Our USB protocol implementations work with our device stack to provide off-the-shelf implementations of a variety of USB functions: networking, storage, audio, video, and so on.

Total System Knowledge

We led the development of a number of important USB specifications for cell phones, cable modems, and LTE modems, and pioneered the first deployments of these specifications.

Our engineers have been helping customers with connectivity technology for twenty years, and have unrivaled know-how and practical insight.

High Volume Quality

Since our establishment in 1995, nearly a billion products have been shipped using MCCI technology. The world’s largest consumer electronics and semiconductor manufacturers depend on us to deliver software that is fast, elegant, portable, and scalable.

Our software is deployed as part of Windows 10 for Raspberry Pi, in smart phones, LTE data cards, PCs, WiGig WSE docks, set-top boxes, car navi systems, satellite systems, digital image transfer, and test equipment.
