The patch in the following e-mail fixes a reference count bug, it seems to me that uvc_unregister_video is a good location to release the final reference, I find it is called once. It may sound like a lot to plug and unplug the USB camera 250 some times, but in my case "disabled by hub (EMI?), re-enabling..." kept unplugging and plugging in the device until days later it ran out of minors and I lost the video security feed. With this patch, now that the device is actually being removed other problems are showing up. Specifically the following if the camera is removed or `rmmod ehci_pci` while an application is getting video from it. It doesn't happen if the camera is not in use. How do I track that down? sysfs group 'power' not found for kobject 'event10' sysfs group 'power' not found for kobject 'input32' sysfs group 'id' not found for kobject 'input32' sysfs group 'capabilities' not found for kobject 'input32' sysfs group 'power' not found for kobject 'media0' -- David Fries <david@xxxxxxxxx>
