Jeff> I'm trying out the "net" backend of the .72 release with a<br>
|
|
Jeff> Microtek E3, Adaptec 2940, and Redhat Linux 5.0. It starts to<br>
|
|
Jeff> work (in the "Preview" dialog of xscanimage); but after what<br>
|
|
Jeff> seems like one pass, xscanimage freezes up. From then on, the<br>
|
|
Jeff> scanner is unusable until I reboot. If I try "scanimage -L",<br>
|
|
Jeff> scanimage just hangs until I kill it.<br>
|
|
<p>
|
|
Jeff> Scanimage works fine if I use the Microtek backend directly.<br>
|
|
<p>
|
|
I just (re-)tested it with the Mustek backend and all is fine here.<br>
|
|
When writing the Mustek backend, I found that scanning through saned<br>
|
|
uncovered some bugs in the Mustek that did not show up in testing with<br>
|
|
scanimage or xscanimage. As a result, I'd highly recommend testing a<br>
|
|
backend through saned as it will increase the likelihood that the<br>
|
|
backend does indeed work according to the SANE API spec.<br>
|
|
<p>
|
|
I'm not saying this is necessarily a bug in the Microtek backend, but<br>
|
|
just because it works with scanimage doesn't prove that it's a bug in<br>
|
|
the net backend or in saned either. Maybe you can try to use<br>
|
|
SANE_DEBUG_NET=128 on the client side and/or "saned -d 128" on the<br>
|
|
server side to try to track the problem down?<br>
