Hi,
I've cross compiled UVC driver for ARM arch, using kernel 2.6.14.
I'm using uvccapture to get snapshot by a FinePix E550 camera in webcam mode.

After the command ./uvccapture -v , the output is:

Using videodevice: /dev/video0
Saving images to: snap.jpg
Image size: 320x240
Taking snapshot every 0 seconds
Taking images using mmap
 format asked unavailable get width 352 height 288
Resetting camera settings
ioctl querycontrol error 22
ioctl querycontrol error 22
ioctl querycontrol error 22
ioctl querycontrol error 22
ioctl querycontrol error 22
Camera brightness level is -1
ioctl querycontrol error 22
Camera contrast level is -1
ioctl querycontrol error 22
Camera saturation level is -1
ioctl querycontrol error 22
Camera gain level is -1
Saving image to: snap.jpg


I get the snap, but there are these errors about the camera settings.

How can I fix it?

Thank you for any suggestion.

Best Regards,
Claudio Montemaggiore
