Hi,All I can tell you at the moment are that they are files that seem to indicate what the OS has found on the machine. I haven't figured out how they are used. The sysconfig/hwconf file shows all the devices connected to the machine, including the scanner.

I installed Red Hat Linux 8.0 on my computer and can't get SANE to recognize the UMAX Astra 3400 scanner attached to the USB port. Here's what I know:
etc/sysconfig/hwconf shows a "UMAX USB SCANNER" attached to the USB port, of "OTHER" class and "unknown" driver.
The file "/usr/share/hwdata/usb.ids" did not include the UMAX 3400, although other UMAX scanners were there. So I modified it. It is now included.
I don't know these files. Are they used for hardware
detection/hotplugging?
"sane-find-scanner" returns an information message, but does not identify the scanner.
So your scanner wasn't detected by the kernel at all. By the way: Which kernel version?
Red Hat 8.0 uses kernel 2.4.18-14. I'm a little surprised at your comment. I would have thought that finding the scanner in the hwconf file and not detecting it with sane-find-scanner would say that the kernel detected it but SANE did not.
First, when I tried to run rmmod scanner the system said "command not found," even when I tried it from the /sbin directory. I tried to run modprobe and got the same response. However, again, with the scanner vendor and product id's correctly entered in the hwconf file, doesn't the kernel already know it's there?
First make sure, that your scanner is detected by the kernel. Run
"rmmod scanner" to unload the kernel scanner module. Then run
"modprobe scanner vendor=0x1606 product=0x0060" to tell the scanner
module about your scanner. Now sane-find-scanner should find your
scanner. Set up plustek.conf as necessary (probably you need to change
/dev/usbscanner to /dev/usb/scanner0).
Second, I looked at the plustek.conf file and found that it already has the /dev/usb/scanner0 line. But my problem really seems to be getting SANE to run the Plustek script for the UMAX scanner. How do I establish that relationship?
How do I get SANE (which apparently stands for Scanner Access NOT Easy)My comment was certainly not intended to insult anyone. I am well aware of the freely given time and effort of the entire Linux development community and am as grateful for it as anyone. But please, lighten up :-)
It doesn't help to grumble about SANE if the people that may help are most probably SANE users or developers :-) Especially if SANE is not involved at all (but the kernel).
I looked at that file and found that the scanner is included in the list, with the vendor and product id's you mentioned earlier.to realize that there really is a scanner attached to the USB port and that it needs to run the Plustek driver to communicate? Any help will be appreciated.
You can also look at what's connected to your system by running "cat
/proc/bus/usb/devices". There you should find the ids of your scanner,
in case I gave you the wrong ones. If this file doesn't exist, run
"mount -t usbdevfs /proc/bus/usb /proc/bus/usb".
More information is in /usr/src/linux/Documentation/usb/scanner.txt,The scanner.txt document is not included in the Red Hat installation. I've looked at other documents (several times) and haven't found what I need yet.
man sane-usb, man sane-plustek.
I very much appreciate that you took the time to respond. Thank you.
Rich
