USB

Intelligraphics has provided dozens of USB 1.1 and 2.0 solutions to our customers across a variety of leading PC and embedded operating systems. Our team of veteran device driver experts has worked with a number of manufacturers of USB driver hardware providing low-speed, full-speed, and high-speed USB driver/firmware solutions for device classes which include HID, scanners, video capture hardware, printers, monitors and hubs. Intelligraphics also has extensive experience working with customers designing and implementing USB core logic, firmware and drivers for custom device solutions.


USB On-The-Go


Intelligraphics took an early lead providing USB On-The-Go solutions to manufacturers of cutting-edge OTG hardware, having implemented one of the first embedded USB On-The-Go solutions available in the industry. As we have successfully overcome the learning curve for this exciting technology including SRP and HNP protocols, Intelligraphics is a primary provider of USB On-The-Go drivers and firmware solutions to hardware and system manufacturers alike.

USB Electrical and Protocol USB.ORG tests preparation and pre-qualification


Intelligraphics has the expertise and the equipment to pre-qualify USB low/high/full-speed devices and chipsets for obtaining USB.ORG logo. The company has a test USB lab, equipped with high-speed oscilloscopes, USB analyzers and test fixtures/boards to verify and prequalify USB peripherals, chipsets and boards. If the firmware and the drivers do not have the required test routines, Intelligraphics extends its functionality. After the electrical and protocol testing of the USB Peripheral/Host/OTG devices, specially designed benchmark routines are executed to stress test the devices and identify performance and functionality bottlenecks. These tests helps our partners to deliver well tested, performing and reliable USB products.

USB Silicon IP Support and Verification


Intelligraphics has worked with major silicon IP providers and their clients to help customize their IP and verify the silicon before (at FPGA stage) and after “first chip” tape-out. The company is very familiar with Mentor Graphics and Synopsys USB IPs and its drivers.
