I have an old Acer S2W 3300 U scanner that I used to use in Linux some ten years ago. Tried to install it in an updated Slackware64 linux box, but the kernel doesn't seem to be able to identify it.

 # uname -a                                                                          
Linux leao 4.4.38 #2 SMP Sun Dec 11 16:11:02 CST 2016 x86_64 Intel(R) Xeon(R) CPU E3-1246 v3 @ 3.50GHz GenuineIntel GNU/Linux


# grep -v '^#' /etc/sane.d/snapscan.conf | head  -6                                 

firmware /usr/share/sane/snapscan/u176v046.bin
/dev/usb/scanner0 bus=usb



# ls -l /usr/share/sane/snapscan/u176v046.bin

# dmesg | tail

Can I have any hope to make this work?

  • Looks like a hardware problem in the scanner / USB connection. Did you try a different cable (on the low chance it's the cable)? – dirkt Dec 21 '16 at 18:49
  • @dirkt: It's not the cable. Thank you for your interest! – Luis Dec 22 '16 at 12:50
