Isn't the "Standard VGA card" appearing in device manager a standarized device class (that is used when no drivers are installed for the graphics card)? It would actually be cool if somebody could implement a VGA gadget driver that works on both windows and linux out of the box (when plugged in), because it could be useful in a lot of situations, everything from game streaming to remote computer control. For the ConfigFS, I think the best would be a option to supply the supported resolutions and rates as a "descriptor". Anything more isn't really needed, and the easiest way to supply the picture to the operating system would be via a /dev/video0 output that works like a v4l webcam, but that shows the picture that the host PC (which is connected to the OTG input of the linux device) is sending to it. -----Ursprungligt meddelande----- Från: linux-usb-owner@xxxxxxxxxxxxxxx <linux-usb-owner@xxxxxxxxxxxxxxx> För Clemens Ladisch Skickat: den 2 juli 2018 08:28 Till: linux-usb@xxxxxxxxxxxxxxx Ämne: Re: USB Gadget driver for USB screen?

You could try reverse engineering the protocol used by the sisusbvga or udl drivers, and implementing that.
