Error while initializing Motion

Question

Jul  6 18:32:19 server motion: [0] ioctl (VIDIOCGCAP): Invalid argument
Jul  6 18:32:19 server motion: [0] Capture error Invalid argument

This does mean that my camera driver is broken?

I'm using a camera based on Sonix SN9x102 chipset with a Kernel 2.6.12.2 built-in drivers. kernel messages after inserting usb-device:

Jul  6 18:31:24 server kernel: usb 1-2: new full speed USB device using uhci_hcd and address 3

Answer

I do not know the driver from personal use. Motion still only support the V4L API. Not V4L2 (Video for Linux version 2). PerJonsson is working on it and eventually Motion will support V4L2. So you need to use a driver which is backwards compatible - if it exists.
