> It seems like that would be a reasonable label, but the description you provided isn't so helpful. Do you know what kernel module handles support for this device? Is it something under drivers/media? Alternatively, do you have examples of devices that are accessed through this node? From what I can google, it seems to support v4l_device_t, but I'd like a little more assurance.
