KVM
Keyboard & Mouse Control
The USBridge appliance operates as a composite USB Human Interface Device (HID). This hardware-level emulation guarantees native, driverless compatibility directly at the BIOS, UEFI, and bootloader stages of the target host.
Mouse Control
For interaction with graphical user interfaces (GUI) and OS installers, the appliance supports two distinct cursor positioning algorithms to match different host behaviors.
Absolute Mode (Default)
In absolute tracking mode, the device sends exact X/Y coordinate data to the target machine. This replicates standard touch-panel behavior, ensuring the remote cursor maps perfectly 1:1 with your local browser or client cursor. This is the recommended mode for modern operating systems.
Relative Mode
In relative tracking mode, the device transmits only the movement delta (directional shifts) relative to the current cursor position. This matches the behavior of a classic wired physical mouse and is often required for legacy interfaces, older BIOS menus, or specific low-level recovery environments that do not support absolute coordinate mapping.
Keyboard and Text Input
Keyboard emulation is strictly optimized for critical pre-OS operations, leveraging USB HID Boot Protocol compatibility to ensure deterministic input before any OS-level USB drivers are loaded.
Compatibility and Layout
The virtual keyboard input is engineered to function flawlessly inside text-based UEFI menus, terminal interfaces, and bare-metal OS installers where advanced, software-dependent HID features are unavailable.
Paste from Host (Clipboard Passthrough)
To accelerate bare-metal provisioning and repetitive administrative tasks, the client includes a clipboard passthrough mechanism. This feature allows you to seamlessly inject long configuration strings, complex passwords, and CLI commands directly from your local workstation into the remote target terminal as rapid keystrokes.
