Hi, Gerard, thanks for the reply!
I read the README.linux, but it mainly only addresses permission issues,
and I'm running as root (for now, until I get it working). Ditto
hotplug and permissions on /proc/bus/usb/001/002. libusb must be working
OK if sane-find-scanner finds the scanner, right? if not, where do I
look to get it working with sane?
Another thread with similar problems talked of "emerging" libusb and
xsane, but that was GenToo and I'm running Mandrake - I've never heard
Shouldn't this be simple?
