USB Keyboard Platform
Client: Consumer Electronics Company
Overview
Consumer peripherals live or die by compatibility. When off-the-shelf USB stacks couldn't meet the requirements, we built a custom USB HID implementation from the ground up, tested against dozens of host configurations to ensure the keyboard works everywhere.

The Challenge
A keyboard that doesn't work on a customer's computer is a returned keyboard. Consumer USB peripherals must work flawlessly with every host controller and operating system in the market, including legacy systems and edge-case embedded hosts. Off-the-shelf USB stacks carry subtle compatibility bugs that only surface with specific hardware. The product needed zero-install operation across Windows, macOS, Linux, and various embedded hosts.
The Solution
We built a custom USB HID stack with meticulous attention to the timing, descriptor formatting, and protocol edge cases that trip up certain host controllers. Extensive compatibility testing across dozens of host configurations, including known-problematic systems, ensured the keyboard works reliably before it ever hits the production line.
