The Intrepid Ibex 8.10 release came out last month. It would be great if
you could test and confirm if this is still an issue? You should be able
to test using a LiveCD. Please let us know your results. For now, I'm
going to move this bug forward to target the actively developed linux
kernel package. During the Intrepid development cycle the linux-ubuntu-
modules package was merged with the linux kernel package. Thanks.

** Changed in: linux (Ubuntu)
Sourcepackagename: linux-ubuntu-modules-2.6.24 => linux
       Status: Confirmed => Incomplete

Bug description:
The isight firmware gets loaded correctly but it fails to register a video device:
[   62.810912] uvcvideo: No valid video chain found.

My system is up2date as of today.

Linux helios 2.6.24-16-generic #1 SMP Thu Apr 10 13:23:42 UTC 2008 i686 GNU/Linux

The driver fails in uvc_driver.c:
list_for_each_entry(streaming, &dev->streaming, list) {
                        if (streaming->header.bTerminalLink == term->id) {
                                dev->video.streaming = streaming;
                                found = 1;
                                break;
                        }
                }

                if (found)
                        break;
        }

        if (!found) {
                uvc_printk(KERN_INFO, "No valid video chain found.\n");
                return -1;
        }

I will attach lsusb -vv
