@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.
@onfy the really bad ones yes
@unascribed @onfy it basically just dumps raw framebuffers into the thing which works since it's USB3
@noiob @unascribed Ah, I had older generation USB 2 devices in mind, which obviously can't do that.
@noiob @onfy ok, the part i can read tells me what i want to know
namely, that it's a UVC device, same as a webcam, but it has endpoints that go the other way
so that tells me which USB IF spec I need to read and where I need to be looking in the gadget system
