RPi & Video Grabber (USB)

[makgab]

Hi!

I am trying a RPi (B, 512MB RAM) + TFT (on GPIO) + USB Video Grabber.
If I try connect the Grabber then the RPi reset. So I shutdown the RPi and connect the Grabber, then RPi is starting. Ok.
But the Grabber is not available, no file "/dev/video0".
If I connect the Grabber to my Fedora 20 x64 machine, the Grabber works fine!

Code: Select all

# dmesg
...
[40952.435828] usb 2-1.1: new high-speed USB device number 14 using ehci-pci

[40952.873609] cx25840 6-0044: Firmware download size changed to 16 bytes max length

So, the driver is the "cx231xx".

I tried the module cx231xx in Raspbian-2014-09-09, it was loading, but no device file (/dev/video0):

Code: Select all

# modprobe cx231xxx
# dmesg
media: Linux media interface: v0.10
Linux video capture interface: v2.00
usbcore: registered new interface driver cx231xx

What can I do for grabber can access?

Try it on a powered hub, it sounds like your Model B can't power it.

If that still does not work, you may need a different V4L driver.

With powered hub is same...
No /dev/video0 device. Why? What do I need to do?

Which v4l driver do I try it with?
