Dino-lite UVC kernel patch

Linux UVC Video module patch for legacy dino-lite cameras. The patch enables controlling LED light through uvcvideo. The project uses DKMS (Dynamic kernel module system) to automatically build the patched module after the kernel was updated. The repository contains the config, the prebuild script, and the patch that need to be copied into /usr/src/

Original patch | UVC | DKMS

Kernel: >5.15 | UVCVideo: 1.1.1

Steps for Ubuntu/Debian

1. Download the zip file from this repository and extract to /usr/src/uvcvideo-1.1.1-dinolite

2. Install dkms, wget, xz-utils, linux-headers-generic and run dkms install uvcvideo/1.1.1-dinolite If uname -r does not match the kernel headers found in /lib/modules/, use dkms install -k <x.y.z-tag> uvcvideo/1.1.1-dinolite

3. Test the patched UVC module using:

Turn on LED

uvcdynctrl -S 4:3 8001f1

Turn off LED

uvcdynctrl -S 4:3 8001f0`
