Dear Julien, dear all,
I also cc this message to the adress that is indicated for bugs
information on the SANE/avision backend page.
Julien, thanks for the help. Looking at doc/descriptions/avision.desc
in the source tree, the file says it is actually computed automatically
from avision.c
As a matter of fact, only the HP 8250 & 8290 are mentionned in
doc/descriptions/avision.desc although the HP 8270 is mentionned in
avision.c so I tried modifying avision.c (basic modifications)
according to how I thought it may have any impact on this issue to no
avail... I also tried to add the parts corresponding to the 8270
checking for the correct model number directly into avision.desc,
recompiling and reinstalling, to no avail neither.
Then I tried recompiling the package with the original development
files for the avision backend and it suddenly started working as a
regular user (but I'm perfectly unable to locate the reason why it
worked as I thought I came back to the original situation),
recognizing the scanner as a 8200 model (generic I suppose).
However, now after rebooting the computer it continues working
only as root and can not access the usb port as a regular user (back as
it was before) for this scanner...
Any hint ?
I've now tried recompiling again and again but still no access as a
regular user... I only I knew what had changed when it was working...
I can send log files if you're insterested.
As a matter of fact (but it may be pointless), though there are lines
like the following in avision.c:
#ifdef FAKE_ENTRIES_FOR_DESC_GENERATION
{ "HP", "C9930A",
0x03f0, 0x0b01,
"Hewlett-Packard", "ScanJet 8250",
0,0},
/* comment="1 pass, 4800 (?) dpi - USB 2.0" */
/* status="good" */
#endif
{ "HP", "C9930A",
0x03f0, 0x3905,
"Hewlett-Packard", "ScanJet 8270",
0,0},
/* comment="1 pass, 4800 (?) dpi - USB 2.0" */
/* status="good" */
#ifdef FAKE_ENTRIES_FOR_DESC_GENERATION
{ "HP", "C9930A",
0x03f0, 0x0b01,
"Hewlett-Packard", "ScanJet 8290",
0,0},
/* comment="1 pass, 4800 (?) dpi - USB 2.0 and SCSI - only SCSI
tested so far" */ /* status="good" */
#endif
There is no such thing as:
:model "ScanJet 8270"
:interface "USB"
:usbid "0x03f0" "0x3905"
:comment "1 pass, 4800 (?) dpi - USB 2.0"
:status :good
and only 8250 and 8290 parts are present in avision.desc
Yours sincerely.
Olivier.
