<p>
That's bad :( . There are or have been situations, where the backend hangs,<br>
mainly due to SCSI problems, or a bug in the backend, when executing<br>
a SCSI command. However, this does not seem to be such a situation.<br>
<p>
Immediately after this "read system status" command, which is successfully<br>
executed (because there is a result), the function sane_get_devices()<br>
returns control to xscanimage, which should then present the available<br>
devices to the user.<br>
<p>
I will have to think about this and will contact you directly (probably<br>
the next weekend) to make some suggestions how to proceed further.<br>
<p>
One thing you could try is to call xscanimage directly with<br>
<p>
xscanimage microtek2:/dev/sgd (this was the device, IIRC)<br>
<p>
I think, that the frontend then skips the whole sane_get_devices()<br>
function, that causes the hang.<br>
