@unascribed Isn't it some PCI to USB bridge?
@unascribed Or do you mean those really bad ones. I think those use a custom driver to do compression.
@unascribed @onfy the local CCC took some apart but the docs are mostly in German https://wiki.aachen.ccc.de/doku.php?id=projekte:usb-vga
@noiob @unascribed Ah, I had older generation USB 2 devices in mind, which obviously can't do that.
@unascribed @onfy it basically just dumps raw framebuffers into the thing which works since it's USB3
