I'm very interested in a permanent solution, and would love to be able to scan double sided...which you will also find doesn't work. The HP8250 is a great scanner, as I'm sure the HP8270 is. My recollection is that a developer was willing to fix these if he had a scanner, or barring that, USBsnoop of the scanner working. That was over a year ago. I don't have a XP or windows machine to run USBsnoop on, so I haven't been able to do any data gathering. My situation may change.<br>
<br>Meanwhile I can say that despite the shortcomings, I use my HP8250 scanners almost every day, and they are great with xsane. I only wish I had full functionality! But I'm thankful that I have what I do.<br><br><br>

Hi,<br>
it worked like you said but this is not really a permanent fix for me.<br>
I guess this confirms that the bug is somewhere in the scanner<br>
initialization part of the sane/avision code.<br>
<br>
I'll try to check out and see if I can understand the code in the<br>
library and maybe make it work...<br>
Meanwhile, if somebody has experience with this and want's to help out<br>
I can give access to the machine connected to the scanner for debug<br>
purposes.<br>
<br>
Quick solution for me would be to buy another scanner that works well<br>
with ADF but I'd really like to fix this issue with the HP as well.<br>
Can you guys recommend another good scanner proven to work well with<br>
adf/sane in linux (preferably same environment as mine).<br>
<br>
Thanks,<br>
