uvcvideo driver broken for ReadyNas 2.6.37.6.RNx86_64.2.2

Hi Guys,

I am helping a friend get his ReadyNAS Ultra 2 working with kmotion, for that he needed uvcvideo which has been installed AOK

However there is no trace of /dev/video0, so investigating a little further I get ...

ReadyNas:~# uname -a
Linux ReadyNas 2.6.37.6.RNx86_64.2.2 #1 SMP Thu Mar 8 00:29:52 PST 2012 x86_64 GNU/Linux

ReadyNas:/# modprobe uvcvideo
WARNING: Error inserting videodev (/lib/modules/2.6.37.6.RNx86_64.2.2/kernel/drivers/media/video/videodev.ko): Invalid argument
FATAL: Error inserting uvcvideo (/lib/modules/2.6.37.6.RNx86_64.2.2/kernel/drivers/media/video/uvc/uvcvideo.ko): Unknown symbol in module, or unknown parameter (see dmesg)

And the tail of dmesg ...

uvcvideo: Unknown symbol video_usercopy (err 0)
uvcvideo: Unknown symbol video_device_release (err 0)

It looks to me that the uvcvideo driver has a problem, Its been a long while since I compiled anything but unknown symbol makes me think it is not compiled for this kernel ?

Can anybody advise or point me to the package maintainer ?

Cheers
