Usb 1-1.2.2: New USB device found, idVendor=17e9, idProduct=03f9, bcdDevice= 1.12 Usb 1-1.2.2: new high-speed USB device number 14 using dwc_otg Usb 1-1.2.1: Manufacturer: Silicon Integrated System Co. Usb 1-1.2.1: Product: SiS HID Touch Controller Usb 1-1.2.1: New USB device strings: Mfr=1, Product=2, SerialNumber=0 Usb 1-1.2.1: new full-speed USB device number 13 using dwc_otg When you connect the USB cables to the Pi, the screen will be recognized as 2 devices (1) touch (2) screen: Note: we used a Raspberry Pi 3 B+ with Buster OS Udlfb driver talks to the DisplayLink screen via USB and exposes that interface through the Linux framebuffer device at you just need a way for your Raspberry Pi system to output whatever you want to display to a framebuffer. In Linux, the DisplayLink device appears to the system as a framebuffer, which is a hardware-independent API for accessing video memory, a.k.a.

This module should already be there on recent Raspbian builds I didn’t have to do anything to get it. In Linux, the driver that you need is called udlfb, which is provided as a kernel module. Windows has DisplayLink support built in, but other operating systems typically need some added software to make it go.
DISPLAYLINK USB GRAPHICS SOFTWARE FOR LINUX GREEN SCREEN DRIVERS
Note: this screen uses 2 USB ports to get the 1A (due to 500MA max rating for USB port)ĭisplayLink is a proprietary USB graphics chip with associated drivers and protocol.

So, for our example we use a ELO 7″ 5V 1A ET0702L screen with a resolution of 800×480 pixels: In the days of 2012-2016 it could be a struggle to get a displayLink scrren working, needed to compile the Linux core again with some “udlfb” libs, well….it seems all integrated out of the box these days!, you just need to adjust some settings.
