Hi Anndras,<br>
|
||
<p>
|
||
this should say: found processor "HP C2520A 3503"<br>
|
||
So the find-scanner tool may also encounter the problems.<br>

|

The 00-character is definitely wrong. The scanner should respond with a<br>
|
||
'V' at that place like:<br>
|
||
<p>
|
||
[hp] scsi_read: 16 bytes:<br>
|
||
0x0000 1B 2A 73 32 35 37 64 30 56 50 20 20 20 20 20 20 .*s257d0VP<br>

<p>

There could be several problems:<br>
|
||
- the backend has problems with the DEC-Alpha architecture. But I think<br>
|
||
there are other Alpha-users which use HP-scanners.<br>
|
||
- Timing problems with read operations. It seems that the scanner has<br>
|
||
recognized the Reset (EscE) and the inquire error stack command<br>
|
||
(Esc*s257E). The beginning of the response is ok. But it is incomplete.<br>
|
||
I have posted this to the sane-devel mailing list. Maybe someone knows a<br>
|
||
solution to that problem.<br>
|
||
<p>
|
||
Sincerely<br>
|
