USB scanners not coming through on LTSP clients

Question

Have 30 workstations all running nicely on LTSP, each running ubuntu. Bought 5 Epson V33 scanners, which of course worked fine on local ubuntu installs.

When these clients are running through LTSP the scanners are not detected.

Can anyone lend a hand with this? or give any ideas?

USB flash drives, keyboards , mice etc all come through nicely .

Thanks in advance

I'm having the same problem with an Epson GT-1500 and I've found a solution which works, although not the best solution.

I had to install special epson drivers for my scanner into my chroot area for the clients (Refer: http://download.ebz.epson.net/dsc/search/01/search/?OSC=LX)

Downloaded my drivers, copied them into my chroot section and installed with the following commands:

sudo apt-get install xsltproc
sudo dpkg -i iscan*

Once I had that installed I had to rebuild my ltsp image, reboot the client, then once the client was up I had to replug the scanner in. Then I could start simple scan locally and it would work.

 ltsp-localapp simple-scan

Make sure you scanner is coming up on the client

 ltsp-localapp xterm

Then within xterm

sane-find-scanner

You should see your scanner in here.
