From the project
BenchSwitch USB DUT Hub: a four-port USB 2.0 hardware development prototype with KiCad design sources, BOM, manufacturing files, and bring-up documentation.
A four-port USB 2.0 DUT hub for embedded firmware development and automated hardware testing.
BenchSwitch was born from a practical need in agentic firmware development: let the development workflow power-cycle a device instead of waiting for someone to unplug it. The design combines a USB2514B hub controller with individually switched downstream power, targeting host control through tools such as uhubctl.
