Hi,

The failing ioctls are (only 2 are sent down from Skype):

Creating /dev/video0
mydebug: v4b_open fflags: 00000003
mydebug: linux_open: handle=28c08600
mydebug: v4b_ioctl: handle=28c08600 cmd=0x40047601
mydebug: linux_ioctl returns: error=ffffffea
mydebug: v4b_convert_error: CUSE_ERR_INVALID
mydebug: v4b_ioctl: handle=28c08600 cmd=0x403c7601
mydebug: linux_ioctl returns: error=ffffffea
mydebug: v4b_convert_error: CUSE_ERR_INVALID
mydebug: v4b_close: handle=28c08600

(cmd is printed as 'cmd=0x%08x')

what maybe wrong with the cmd's?

Thanks

	matthias
