<p dir="ltr">Hi Rolf, </p>
<p dir="ltr">Can you point to a short guide for getting proper USB logfiles? </p>
<p dir="ltr">Meanwhile, I noticed that wireshark do not have full support for BJNP. I browsed SANE and CUPS sources, and the BJNP dissector, and maybe in my spare time I'd like to improve the dissector. If you have any unofficial doc or article/analysis about BJNP outside what's already in C sources, I'd like to get some links.</p>

<br>
It seems that we have a general problem with ADF scanning from all<br>
Maxify scanners.<br>
<br>
If possible, please provide USB logfiles from a Windows machine scanning<br>
from ADF and duplex ADF, one page and two pages, using Wireshark. Then I<br>
can try to fix this.<br>
<br>
In the meantime I'll update the doc files.<br>
<br>
Many thanks for your help.<br>
<br>
Cheers,<br>
