Hi, I have an Epson Stylus RX600 (USB connection) and I can't get sane to 
detect it fully. Supposedly this printer is supported with a "good" rating. 
I've spent a lot of time researching this but couldn't solve this problem! 
Please help...

Here is a bunch of info:

I'm using slamd64-10.1 (Slackware distribution tailored for x86_64). I have 
package sane-1.0.14-x86_64-1 installed. My kernel is version

Because I use x86_64 architecture, I can't get the epson drivers at 
http://www.avasys.jp/english/linux_e/dl_spc.html to work for me, as some 
source is available but it depends on proprietary libraries w/o source. 
Therefore, it won't compile. I can try using the binaries but I'm not sure 
how to extract them from rpm, or if I should just install rpm, or if they 
would work even if I extracted them. Also, sane-epson claims that just about 
any epson will work on it, at least at some minimum level of support.

Here is the  USB device info (from /proc/bus/usb/devices):

sane-find-scanner reports this:

/dev/usb is very limited:

I altered /etc/sane.d/epson.conf to have every line commented out except for a 
single line: usb 0x4b8 0x806. This doesn't help. I also tried futzing with 
mknod, /dev/usb/scanner, /dev/usb/scanner0, libusb:005:002, etc.. with 
negative results.

scanimage -L always fails!

%scanimage -L
