Whether you are a professional hardware engineer or a DIY tech enthusiast looking to level up your setup, this is an incredibly powerful piece of hardware. These retail for well over $800 new because they aren't your average USB hub—they are completely software-controlled.

*** IMPORTANT NOTE ON ARCHITECTURE: This is a TRUE 2:4 HUB, NOT a standard 1:4 consumer split. It features TWO dedicated upstream host ports (labeled Up 0 and Up 1) allowing you to connect TWO separate computers/hosts simultaneously and programmatically switch control across the 4 downstream ports. ***

What does that actually mean?Have you ever had a USB peripheral, camera, or external drive freeze up, forcing you to physically unplug it? With this industrial-grade hub, you can completely control the power (VBUS) and data lines (D+/D-) for every single port independently using Python, C++, or simple REST APIs.

Great Project Ideas for This Hub:

• Smart Home & Automation Server: Automatically trigger a physical hard-reboot of a frozen device or camera using webhooks from workflow engines like n8n or Node-RED.

• Homelab & Docker Management: Reset or toggle USB peripherals passed through to Docker containers or virtual machines without ever touching a cable.

• Professional QA & Flashing: Perfect for automated HIL (Hardware-In-the-Loop) testing, embedded systems development, and device firmware flashing where dual-host switching is required.

Technical Specifications:

• True 2:4 Dual-Host Architecture: Connect two hosts simultaneously and switch programmatically.

• Independent Port Control: Programmatically enable/disable VBUS and data lines for each port.

• Robust Protection: Built with 30kV ESD protection on all USB connections to handle continuous automated environments.

• API Integration: Fully controllable via Acroname's BrainStem API platform.
