We are experts at developing devices that communicate with a host system via USB.   During our years as Keyspan we developed a family of USB adapters that were known for being the most reliable USB adapters available on the market.   We also developed USB attached IR and RF transceivers and remote controls.
As Redpark we've continued to provide USB expertise to our customers -- engineering custom USB devices, providing USB driver development services, and consulting to systems integrators on projects that involve USB products.
We developed a custom USB adapter that connects a Macintosh computer to a Samsung LCD TV.   The adapter allows an application on the Macintosh to communicate with the LCD TV using the Samsung "AnyNet" prototcol.
We provided a USB-attached infrared transceiver and custom USB drivers to a major consumer electonics company.   The transceiver enables an application on the PC to receive infrared data from an IR remote, and to issue IR commands to a TV or cable box.
We developed custom RF remote controls with an RF receiver that attaches to the USB port on a PC or Mac.   The remotes appear as a USB HID device to the PC.
We provided consulting services to a systems integrator that was struggling to get numerous USB devices to work together properly.   We helped to identify revisions that needed to be made to the USB device drivers in order to attain compatibility.
