Beaglebonebone black USB Camera doesnt work

Hi,

You should load the v4l2 & usb drivers with either insmod or modprobe.

After that refer to the following link for example gst pipelines: processors.wiki.ti.com/.../ARM_Multimedia_Peripheral_Examples

Thank you for your answer Yordan.

But my problem is I coulndt install drivers. How can I load them ? 

I found that drivers are at /lib/modules/'uname -r'/kernel/drivers/media 

v4l2 and usb drivers are here, but I couldnt load them with insmod or modprobe.

Best Regards,

Hi,

Can you share the console output, when you try insmod or modprobe?

Hi,

Now, I installed modules with insmod and below is my lsmod output. But problem still occurs there is no /dev/video0 or /dev/v4l file.

After each reboot, I needed to insmod all modules in /lib/modules.../kernel/drivers/media then I added them to end of /etc/init.d/rc file, is this correct?


I think linux knows camera.

Why this /dev/video0 is not seen?

Please check if your camera is supported here: www.ideasonboard.org/.../

Hi,

Ubuntu and internal beaglebone black linux recognize it and creates /dev/video0 . I also disabled uvcvideo and only gspca driver is loaded result is same. I can not understand why linux doesnt recognize usb cam? When I plugged it to board it gives:

[ 314.840164] usb 1-1: USB disconnect, device number 2
[ 319.801875] usb 1-1: new full-speed USB device number 3 using musb-hdrc

[ 319.958294] usb 1-1: Product: PC Camera
[ 319.962249] usb 1-1: Manufacturer: Vimicro Corp.

Is it resolved when I build all modules to kernel on menuconfig ?

Best Regards,
Ümit.

Check this wiki for configuration: processors.wiki.ti.com/.../Usbgeneralpage

hi,

All is same with the article, and I think both gspca and uvc was selected on kernel.
