[sane-devel] Request for help with Ubuntu 14.04, Xsane and an Epson Perfection V33

Fri Jun 6 07:15:05 UTC 2014

HI,

I am experiencing difficulty in making my current hardware/software 
configuration operate with my Epson Perfection V33 scanner.  The same 
scanner operated fine with Ubuntu 14.04 and my old PC but I cannot get 
it to work using my new hardware.

I am trying to run Xsane but the error I am being returned is " Failed 
to open device 'epkowa:interpreter:003:007':Error during device I/O" . 
The scanner is connected using USB and of course is turned on. I will 
give you as much detail as I am able.

Before attempting to run Xsane I have loaded the following files:
iscan-data_1.15.0-2_all.deb
icc-profiles_2.0.1-1_all.deb
iscan_2.28.1-3.ltdl7_amd64.deb
esci-interpreter-perfection-v330_0.2.0-1_amd64.deb

Each file runs without any indicated error.

My system details are:

It may be of interest that my machine is set up for dual boot to Windows 
8.1. If I boot into Windows the scanner works normally. This would 
suggest that I do not have a hardware problem I think.

The dual boot setup has Windows on one 256G SSD and Ubuntu on a separate 
256G SSD so there should not be any crossover between them. Grub seems 
happy with that arrangement too.

I also have 1TB and 2TB data drives. Both these are formatted to EXT4.

I have tested all the USB ports on my machine with the scanner. There 
are 6 ports on the back of the machine. Four are USB 3.0 and two are USB 
2.0/1.1. I have 3 USB ports on the front of the machine 2 are USB 3.0 
and 1 is USB 2.0

After a cold boot I attached the scanner to what I believe is a USB 2.0 
port and the system initiated, Xsane ran and I was able to scan a 
document successfully (colour). I continued to test other ports with the 
machine reporting I/O errors for all the other ports (including those I 
believed to be USB 2.0/1.1. I then tried putting the scanner back into 
the original USB 2.0 port and IT reported an I/O error.

All ports seem to work normally with the scanner when I am using Windows 
8.1.

After havin Xsane fail I have reviewed my syslog and found this:

rounding interval to 128 microframes, ep desc says 255 microframes

It would seem I am having some problems with my USB ports but I have no 
idea how to deal with it. Strangely all my other usb based devices are 
happy.

I will be very grateful for any advice you may be able to give me.

Regards,

Roger.
