USBridge-KVM 2.0 is a compact, professional-grade stack for system debugging and direct infrastructure control at the most fundamental level (Layer 0). We want to give administrators absolute control over the hardware, bypassing the operating system while ensuring strict hardware isolation.

The device provides out-of-the-box server access with ultra-low latency streaming and the ability to deploy scripts or AI agents to automate routine, low-level tasks.

Reach Out and Administrate (or Game)

Forget about "jelly" cursors, video stutters, and input desync— USBridge-KVM 2.0 is the first hardware KVM-over-IP featuring native, on-board integration of the Moonlight protocol.

The hardware video capture and transmission pipeline is optimized to reduce latency to an imperceptible level. You get the absolute responsiveness of a direct connection: crystal-smooth mouse movement and instantaneous text input response. The latency is so unnoticeable that the bandwidth and reaction speed are enough even for comfortable gameplay in dynamic platformers like Hollow Knight: Silksong — let alone flawless server administration.

By leveraging universal hardware emulation, USBridge-KVM 2.0 bypasses the traditional limitations of proprietary IPMI/iLO solutions—it works on any hardware without requiring drivers. The terminal-based output allows you to copy serial numbers and error codes directly from the console, while maintaining full control through HID command injection. Our unique BIOS-in-Terminal technology intercepts the raw HDMI video signal at the hardware level. Using an onboard chip with real-time offline OCR, it converts BIOS interfaces and pre-boot environments (Pre-OS) into an interactive, selectable text stream.

Capture Immutable Snapshots

The golden rule of the Immutable Snapshots subsystem is that your data cannot be encrypted or deleted from the outside. During any modification, the system never overwrites the source files; instead, it saves only the delta of changes, instantly freezing the new copy in a read-only state.

Thanks to strict hardware isolation, even if ransomware or an attacker gains full root privileges on the compromised server, they have no physical path to reach the KVM storage. There is no vendor lock-in either: all data is stored using the standard Btrfs file system, meaning your backups remain fully accessible and readable on any standard Linux system.

Mount Local Drives

You no longer need to physically insert USB drives or configure complex network boot (PXE) infrastructure. Universal hardware emulation allows you to mount virtual images directly from your workstation — whether it is a standard installation disc (ISO) or an entire, fully configured OS environment (VDI, VMDK).

The target server sees it instantly as a standard, physically connected hard drive, booting straight from your client machine without any image conversion or time-consuming flashing processes. The high-speed LPDDR4X cache fully compensates for network latency, while the Read-Write Overlay mode redirects all new writes to a separate layer, keeping your source Golden Image completely untouched.

Open Source

We firmly believe in hardware transparency and open development. All schematics, PCB layouts, and 3D enclosure models (STL/STEP) will be fully open to the community. The USBridge-Remote agent application will also be completely open-source.

To ensure long-term security and transparency for our users, the core KVM firmware is scheduled to be released as open-source once the code cleanup is complete. At the same time, the BIOS-in-Terminal module (featuring our proprietary offline OCR algorithms and automation stack) is designed as a closed-source component and will remain proprietary.
