Last week, I posted a message to this list describing a problem where scanimage would not recognize my Hewlett-Packard Scanjet 3570c scanner.
It turned out that the problem was that I had compiled SANE without libusb support enabled. Once I grabbed the libusb-devel package from rpmfind.net and recompiled SANE, it worked fine. It might be helpful to add a note in the sane-project.org documentation section, saying that if you plan to use a USB scanner you must have libusb-devel installed before you compile SANE. Thanks to m. allan noah and anyone else who may have tried to help. jstewart
