May be this can help: Is sane-backend installed at /usr or /usr/local/. I ask you this, because it appears that libusb is installed at /usr and sane-backend doesn't or viceversa. I mean Sane Backend is not using all of the libraries from libusb. You sure that both of them are installed at /usr or /usr/local, i suggested you that both must be installed at /usr.
