Vuescan and latest Linux distros?

[Leonard Evens]

I have been using RedHat Linux with Vuescan sucessfully. But the time
has come for me to upgrade my Linux. RedHat is no longer providing a
distro for individual users and there are several followup distros which
I can use. One is essentially RedHat 9 and should work but it has an
earlier form of the Gimp. Another is Fedora, which is a bit more up to
date.

Has anyone been using Vuescan with one of these Linux distros? Any
problems? I am fairly proficient at getting things to work if there
are no insuperable obstacles.

Using Vuescan 8.0.5 on a Redhat 9 and libusb-0.1.8 installed from sources.
Everything works great.

I'm using Vuescan 8.0 with RedHat 9 and libusb-0.1, which I believe is
the default. I haven't tried a more up to date version of Vuescan. I
am mainly interested in what will happen with Fedora, which is somewhat
beyond RedHat 9.

I am using an Epson 3200. Which scanner are you using?

FYI, the linux kernel has problems with its usb2 driver when managing a
lot of data (like a big scan). By now, I scan only with usb1 drivers, and
it works well.

Don't know if the problem has been fixed on the more recent kernel, but
the bug is known to exist in 2.4 and 2.6 branches.

Hi,

I had been using my Canon CanoScan FS4000US with VueScan on RH 7.3
with great success for many months. I recently upgraded my
workstation from RH 7.3 to Fedora Core 1. Since then VueScan has been
unable to recognize my scanner...

I don't know what the problem is. I just sent a problem report to
Hamrick to see if he has any ideas.

I am using my scanner's SCSI interface. I have the most recent Fedora
kernel. If anyone has any ideas on what may have happened between
RH7.3 and Fedora, let me know. Likewise, if and when I fix his
problem, I'll post the solution.

There are some other alternatives to fedora. I would suggest first
trying RedHat 9, which I presume can still be found. There is
something called Scientific Linux which is basically RedHat 9. You
might be able to get it to work with one of those versions. The
problem may be with the kernel or some module. So knowing at which
kernel it stopped working would be useful.

I plan to set up my laptop with a Linux partition on which to do
testing, but I haven't got around to it yet.

I am more familiar with usb scanners, but if you tell me what error
messages you get in /var/log/messages and whether you can tell if the
system can see the scanner in /proc/scsi/scsi, I might have some
suggestions.

Well, for other reasons, Fedora is what I have and there's no going
back at this point. My only option is to figure out what
broke/changed between RH7.3 and Fedora (and hopefully fix it).

I was thinking about trying my scanner's USB interface... If I don't
make any progress with the SCSI interface soon, I'll try the USB.

/proc/scsi/scsi shows:

Host: scsi0 Channel: 00 Id: 06 Lun: 00
Vendor: CANON Model: IX-40015G Rev:1.07
Type: Scanner ANSI SCSI revision: 02

My procedure is roughly as follows:

reboot
login as my user
su to root, cd to root home
run Vuescan - scanner light starts blinking
insert negative strip holder
scanner light blinks for several seconds then ejects the strip holder
scanner light stops blinking

The relevent /var/log/messages entries are:
