From the project
USB Hub (2x USB-A + 2x USB-C, USB 2.0)
Custom 4-port USB 2.0 hub designed for desk use and monitor-stand mounting.
This project exists because most off-the-shelf hubs did not fit my setup: ports were inconvenient, USB-C required adapters, and one purchased hub regularly stopped working after the host resumed from sleep. The goal here is simple: stable USB 2.0 data ports for everyday hardware tools, with the exact connector layout I need.
