SANE tries to open all the device files that may represent scanners,
e.g. /dev/usb/scanner9 in this case. The kernel scanner driver is just
a bit verbose and tells that there is no scanner at that device file.
In later kernel versions I have disabled that message.

It doesn't harm, it may just slow down the detection of scanners a
bit. If you want to reduce the amount of messages you get, you can
delete some of the device files, e.g. /dev/usb/scanner1 ... scanner15
if you only have one scanner.
