Ok, I found the problem... apparently it isn't enough to open port 6566
on the firewall I've recently configured...

But, I have another issue. Using the kernel scanner driver it scans
fine, but using libusb it its the scanning head hits the end and makes

sane-backends 1.0.15
libusb 0.1.10
kernel 2.4.20-42.9.legacy (Red Hat 9)
