Did you test it? Did you have any problems?

Hello everybody. I tried to port UTV007 driver under kernel 3.4.113 from sources from here. Who are interested in trying this driver, please, write a feedback. Attention, this is just an experimental version. After compile need to run sudo modprobe videobuf2_core sudo modprobe videobuf2_vmalloc sudo insmod usbtv.ko Link to download. I tested this driver under Armbian 5.30 with legacy kernel (3.4.113-sun7i) on Cubieboard2. After command sudo insmod usbtv.ko I have video0 device in device list, and dmesg | tail shows: [116494.293249] Probe routine [116494.298265] usbtv 2-1:1.0: Fushicai USBTV007 Video Grabber And v4l2-ctl --all: Driver Info (not using libv4l2): Driver name : usbtv Card type : usbtv Bus info : usb-sw-ehci-1 Driver version: 3.4.113 Capabilities : 0x85000001 Video Capture Read/Write Streaming Device Capabilities Device Caps : 0x05000001 Video Capture Read/Write Streaming Priority: 2 Video input : 0 (Composite: ok) Video Standard = 0x0000f900 PAL-M/60 NTSC-M/M-JP/443/M-KR Format Video Capture: Width/Height : 720/480 Pixel Format : 'YUYV' Field : Interlaced Bytes per Line : 1440 Size Image : 691200 Colorspace : SMPTE 170M Transfer Function : Default YCbCr Encoding : Default Quantization : Default Streaming Parameters Video Capture: Frames per second: 29.970 (30000/1001) Read buffers : 2 User Controls brightness (int) : min=0 max=1023 step=1 default=448 value=448 flags=slider contrast (int) : min=0 max=1023 step=1 default=464 value=464 flags=slider saturation (int) : min=0 max=1023 step=1 default=512 value=512 flags=slider hue (int) : min=-3583 max=3583 step=1 default=0 value=0 flags=slider sharpness (int) : min=0 max=255 step=1 default=96 value=96 flags=slider

I had tried to boot without camera and dmesg | grep OV5640 displayed: init_sensor - frame_rate: 0, max_win_size: 11 CSI_SUBDEV_PWR_ON! sensor read rety=2 error at sensor_detect chip found is not an target chip CSI_SUBDEV_PWR_OFF! And tried to boot with had connected camera then dmasg | grep OV5640 displayed next: init_sensor - frame_rate: 0, max_win_size: 11 CSI_SUBDEV_PWR_ON! sensor_init 0x0 CSI_SUBDEV_PWR_OFF! Then agian I may list /dev/video0 but no access to this device
