This Google Meet room solution integrates the Lightware Taurus UCX-4x2-HC40 universal switcher with a CTL Meet Compute System (Chromebox running Google Meet OS) to deliver a certified, enterprise-grade video conferencing room with native bring-your-own-device (BYOD) capability. The UCX-4x2-HC40 connects to the Chromebox via USB-only — no network connection required — enabling call-state tracking and automatic peripheral switching without introducing network security concerns or firewall dependencies.

When a Google Meet call is active, the UCX-4×2-HC40 monitors call state via USB HID communication and ensures all room peripherals (camera, microphone, speakerphone) remain under Chromebox control for stable operation. If a user connects a laptop via USB-C to the table box during an active call, the UCX does not interrupt the call. When the room is idle (no active call), a connected laptop automatically gains access to room peripherals and the display, enabling BYOD presentations or use of third-party video conferencing platforms (Zoom, Microsoft Teams, etc.). When a new Google Meet call starts, the UCX seamlessly returns peripheral control to the Chromebox.

This USB-only integration eliminates network configuration complexity — no firewall rules, no IP address management, no VLAN dependencies. The Taurus UCX-4x2-HC40 appears as a certified device in the Google Admin Console, providing IT administrators with unified visibility and device management alongside other Google Meet hardware. The solution scales easily across multiple rooms using the same architecture, supports both single-cable USB-C BYOD and legacy HDMI sources, and provides up to 100W USB-C charging per port for laptop power delivery.

Features

Native Google Meet Certification

Native Google Meet via USB HID (appears in Google Admin Console) for unified device management—no scripts or middleware required.

Call-State Aware Peripheral Switching

Call‑state aware switching toggles camera/mic/speaker between Meet and BYOD without interrupting calls; idle rooms allow instant single‑cable laptop access.

Network-Free USB Control

USB‑only connection to the Chromebox (no Ethernet) removes firewall/VLAN and network‑security issues—control runs over secure USB HID.

One Cable for Video, Data, Power

Single USB‑C via TBX‑M210‑K delivers 4K video, USB 3.1 Gen1 (5 Gbps) data and up to 100W charging; two USB‑C inputs support dual‑laptop workflows.

Reliable USB 3.1 to Remote Peripherals

Extends USB 3.1 Gen1 (5 Gbps) to wall‑mounted cameras with low latency; four Type‑A ports for cameras, speakerphones and peripherals.

Full-Bandwidth 4K Video Switching

4K@60Hz 4:4:4 switching (up to 600 MHz) with HDCP 2.2 and HDR passthrough; dual HDMI outputs for main + confidence displays.

How It Works

When the room is idle — BYOD presentation

A user enters the empty meeting room and connects their laptop to the USB-C cable emerging from the TBX-M210-K table box

The laptop begins charging (up to 100W) and the UCX-4x2-HC40 detects the USB-C connection

Because no Google Meet call is active, the UCX automatically routes video from the laptop to the room display and grants USB access to the room camera and speakerphone

The user launches their preferred video conferencing app (Zoom, Teams, Webex, etc.) or presents local content — the room functions as a fully-featured BYOD workspace

If the user initiates a Google Meet call using the room's touchscreen controller or the Chromebox, the UCX seamlessly transfers peripheral control back to the Chromebox without disconnecting the laptop video signal

Key benefit highlight: Users experience zero-friction BYOD access when the room is idle, with automatic return to native Google Meet control when a call begins — all without IT intervention or manual switching.

Scenario 2: During a Google Meet call — protected native mode

A meeting participant joins a scheduled Google Meet call using the room's touchscreen control panel

The CTL Meet Compute System (Chromebox) starts the call and communicates call state to the UCX-4x2-HC40 via USB HID protocol

The UCX locks all room peripherals (camera, mic, speakerphone) to Chromebox control, ensuring stable call operation

If another user connects a laptop via USB-C to the table box during the active call, the UCX does not interrupt peripheral routing — the laptop gains video output to a secondary display or remains on standby

When the call ends, the UCX detects the idle state and automatically grants the connected laptop access to room peripherals if no new call starts within the switch-back delay period

Key benefit highlight: Active Google Meet calls are protected from accidental peripheral switching, eliminating mid-call disruptions while still allowing flexible BYOD connectivity during idle periods.

Multi-source presentation during a hybrid call

A Google Meet call is in progress with remote participants connected via the Chromebox and room camera

A presenter in the room needs to share content from their laptop — they connect via USB-C to the TBX-M210-K table box

The in-room facilitator uses the touchscreen control panel to switch the room display input from the Chromebox output to the BYOD laptop video signal

Remote participants continue to see the presenter via the room camera (still controlled by the Chromebox), while in-room participants view the laptop content on the main display

The facilitator switches back to the Chromebox output when screen sharing concludes — the call remains uninterrupted throughout the source transition

Key benefit highlight: Hybrid meeting scenarios support both in-room content sharing and remote participant engagement simultaneously, with flexible manual or automated switching between native Meet video and BYOD laptop sources.
