install kernel header files and build tools

# debian
sudo apt install linux-headers-amd64 build-essentials

# fedora (might not be accurate!)
sudo dnf install kernel-devel<kernel_version>

check current kernel version

uname -a

download matching kernel tar file from (kernel)[https://git.kernel.org/pub/scm/linux/kernel/git/stable/linux.git/refs/tags] website.
extracts and change directory to ./drivers/media/usb/uvc/
open uvc_driver.c file and scroll down to find uvc_ids list, then add following like others:

	/* Quanta ACER HD User Facing */
	{ .match_flags 	= USB_DEVICE_ID_MATCH_DEVICE
			| USB_DEVICE_ID_MATCH_INT_INFO,
	  .idVendor = 0x0408,
	  .idProduct = 0x4033,
	  .bInterfaceClass = USB_CLASS_VIDEO,
	  .bInterfaceSubClass = 1,
	  .bInterfaceProtocol =	UVC_PC_PROTOCOL_15,
	  .driver_info = (kernel_ulong_t) &(const struct uvc_device_info ) { .uvc_version = 0x010a, } },

build module with this command:

make -j4 -C /lib/modules/$(uname -r)/build M=$(pwd) modules

copy uvcvideo.ko file to kernel module path

sudo cp uvcvideo.ko /lib/modules/$(uname -r)/kernel/drivers/media/usb/uvc/

change directory to /lib/modules/$(uname -r)/kernel/drivers/media/usb/uvc/
rename old file from uvcvideo.ko.xz to uvcvideo.ko.xz.bak (if required)
rename file name from uvcvideo.ko to uvcvideo.ko.xz (if required)
unload previous module

sudo modprobe -r uvcvideo

use modeprobe command to load kernel module

sudo modprobe uvcvideo
