Source code for Linux here: uvc_3.10

Compile:
1. modify makefile

TARGET=sonix_uvcvideo
KDIR:=$YOUR_OPENWRT_PATH/build_dir/target-mipsel_24kec+dsp_uClibc-0.9.33.2/linux-ramips_rt305x/linux-3.10.49/
PWD:=$(shell pwd)

CCFLAGS += -I $(KDIR)/include/

$(TARGET)-objs  := uvc_driver.o uvc_queue.o uvc_v4l2.o uvc_video.o uvc_ctrl.o \
                  uvc_status.o uvc_isight.o uvc_debugfs.o nalu.o

obj-m:=$(TARGET).o

default:
        make $(CCFLAGS) -C $(KDIR) M=$(PWD) ARCH=mips CROSS_COMPILE=mipsel-openwrt-linux- modules
clean:
        rm -rf *.o *.ko *.mod.* modules.* Module.* .tmp_versions .*.*.cmd

2. make it to create sonix_uvcvideo.ko
3. run on VoCore

opkg install kmod-input-core kmod-video-uvc
insmod sonix_uvcvideo.ko

result:
/dev/video0 is mjpeg stream, /dev/video1 is h264 stream.
also you will find UAC, the 8K onboard microphone in /dev/ folder.

ls /dev/video*
v4l2-ctl --list-formats -d /dev/video0
v4l2-ctl --list-formats -d /dev/video1

opkg install v4l-utils
