On the remote server or virtual machine, the RDCB presents itself as a standard bus driver. It enumerates "Virtual Camera Devices" that mirror the inputs detected by the client-side controller. This allows the remote OS to treat the camera as a local Plug-and-Play device, triggering standard system events (e.g., "New Device Connected") without requiring vendor-specific drivers. remote desktop camera bus

Instead of mapping a specific USB device to the remote host, the RDCB captures the raw video feed at the source (client endpoint), encodes it, and transmits it via a virtual bus driver to the remote session. The remote host sees a generic, high-performance "Virtual Camera" device rather than the specific physical hardware, ensuring universal compatibility regardless of the client's specific webcam model. It enumerates "Virtual Camera Devices" that mirror the
The RDCB works by creating a virtual camera device on the remote desktop that is connected to the client device's camera. When a user requests access to their client device's camera from the remote desktop, the RDCB establishes a connection between the two devices. The client device's camera is then virtualized and presented to the remote desktop as a local camera device.
