Subject: [PATCH] spca5xx patch for “No space left on device” error message

This patch Fixes the bandwidth problem that occurs when other USB devices
are on the same host controller bus as the camera by gradually lowering the
bandwidth requirements of the driver.

When the patch is applied, spca5xx drivers works even when other USB devices
are present on the same host controller bus as the camera.

This patch is currently against the spca5xx-20060501 source.

To apply the patch from your current working directory, with a subdirectory
called spca5xx-20060501 use:
patch -p0 < spca5xx-20060501-vodunvibe-Nospaceleftondevice.patch

To apply the patch, in the spca5xx-20060501 directory use:
patch -p1 < spca5xx-20060501-vodunvibe-Nospaceleftondevice.patch

Bandwidth Problem details:
When other USB devices are present on the same host controller
bus as the camera, the bandwidth requirements of the spca5xx driver
are not being met. The spca5xx driver is asking for more bandwidth
than is available which results in the following error messages:

No space left on device
can't open /dev/video0: No space left on device.
usb_submit_urb(0) ret -28

Thanks,

Launchpad Janitor (janitor) wrote on 2008-08-11: This bug is now reported against the 'linux' package

Beginning with the Hardy Heron 8.04 development cycle, all open Ubuntu kernel bugs need to be reported against the "linux" kernel package. We are automatically migrating this linux-source-2.6.15 kernel bug to the new "linux" package. We appreciate your patience and understanding as we make this transition. Also, if you would be interested in testing the upcoming Intrepid Ibex 8.10 release, it is available at http://www.ubuntu.com/testing . Please let us know your results. Thanks!
