Hi ycp. I'm not sure I understand what you define as the distinction between a video card and an adapter; can you clarify? Other than the fact that DisplayLink HIS Multi-View II gets its input from USB rather than PCIe, it is functionally analogous to other 2D video cards such as 1a03:2000 ASPEED Technology, Inc. ASPEED Graphics Family, which is included on h-node. There are other USB DisplayLink video cards such as 17e9:02ee DisplayLink VGA Display Adapter, and I believe there are other vendors that make similar products, such as Trigger, Fresco, and SiliconMotion.
