Scanning is very slow

[theboomboomcars]

When scanning with my Epson Perfection 3490 scanner it pauses for long periods of time. It does scan and the images are very high quality, but it takes a very long time. When opening xsane it detects the scanner, moves the lamp al little, then sits for about a minute before finishing loading. When I click on the acquire preview button it sits for about a minute before doing anything. Xsane has every appearance of having crashed, doesn't respond to clicks on anything. But eventually it does get the preview. Then when I try to scan the lamp makes one pass then waits for about a minute before making the final pass.

Another thing that I have noticed that may be related to this is that when booting it waits for a while at loading the hald, it waits long enough that the splash screen goes away and it shows me the console messages. Since I think that the hald deals with the USB, and this is a USB scanner there may be a relation between the two pauses.

Here is my lspci with the scanner atatched.

I got the same problem with my Epson Perfection 1260 with Feisty 7.04 64bits. I resolved it by changing warmup time option in /etc/sane.d/plustek.conf (I use Plustek backend) from -1 (automatic warmup) to 5 and it works fine.
If you want to know why automatic warmup takes long time, you can use following command line to get more information:
SANE_DEBUG_PLUSTEK=128 xsane
(replace PLUSTEK by your backend)

Thank you for taking the time to report this bug and helping to make Ubuntu better. You reported this bug a while ago and there hasn't been any activity in it recently. We were wondering is this still an issue for you? Can you try with latest Ubuntu release? Thanks in advance.

I can confirm that this is still an issue in Ubuntu 11.10.

Thanks for the report, can you run "SANE_DEBUG_EPSON=128 xsane" and attach the output to this report? (Or whatever backend you use instead of EPSON)
