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
