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?
