Went to sane-project.org and it is listed as a supported scanner.

when I plugged it in and typed dmesg, I get

usb 1-1.3: new full speed USB device using ehci_hcd and address 16

When I type sane-find-scanner

# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a SCSI driver for your SCSI adapter.
# Also you need support for SCSI Generic (sg) in your operating system.
# If using Linux, try "modprobe sg".

found USB scanner (vendor=0x05da, product=0x30cf) at libusb:001:016
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.

So it is finding it.

But when I type lsmod | grep scanner

it comes up empty. So it looks like perhaps the kernel isn't loading the scanner module?

I'm using the stock kernel for Fedora Core 4. I may not be using the latest patch as I haven't rebooted in quite some time, but uname -r gives

2.6.14-1.1637_FC4

Any help would be appreciated. Could the solution possibly be to just reboot with the scanner connected so that kudzu can find it?

Thanks,

I have a 4850 which is not supported, but this is
what I believe you're supposed to use with a 4800:

ok, but what do I do with that information?
