These messages are generated by the kernel scanner module when SANE
tries to access device files that are currently not in use by that

SANE 1.0.5 wasn't able to automatically scan for USB scanners so the
messages didn't occur.

Everything is ok :-) The driver is just a bit too verbose IMHO.

I will add a paragraph about that message in man sane-usb.
