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.
