1.0.25-git20150811-trusty0 of the SANE packages.<br>
<br>
I do have the scanner working correctly in Windows (in VirtualBox)<br>
with the vendor drivers.<br>
<br>
Any ideas? Is there anything else I can do to debug it? Would it be<br>
helpful to get a USB trace (of the Linux and/or Windows cases)?<br>

Thanks,<br>

    Hello,<br>
<br>
    it is slow and difficult to add support for a scanner just by exchanging USB log. However, having a log could give us an estimate of the work to do:<br>
    see <a href="https://github.com/stefdev49/syseneg/analyze/README.md" rel="noreferrer" target="_blank">https://github.com/stefdev49/syseneg/analyze/README.md</a> for a start. Then post the pcap file in some place where I can grab it.<br>
<br>
Regards,<br>
    Ste<br>
