[sane-devel] Can't use scanner on Mac High Sierra (10.13)

[Tom Myers]

I have been able to build the SANE-Backends-1.0.27 But running it gives a problem on USB scanners. It works fine with network scanner

——————— Building ---------------

./configure BACKENDS="epson2" PRELOADABLE_BACKENDS="epson2" --with-usb
make
make install

Note it would be great if the epson2.desc file be updated for the new 12000XL

:model "Expression 12000XL"
:interface "USB"
:usbid "0x04b8" "0x015b"
:status :good
:comment "overseas version of the DS-G20000"

——————— LibUSB ————
I am using libusb 1.0.21

(found from brew list —versions)

————— Testing -------------

Hi Tom,

I have been able to build the SANE-Backends-1.0.27 But running it
gives a problem on USB scanners. It works fine with network scanner
$B!=!=!=!=!=!=!=(B Building ---------------
./configure BACKENDS="epson2" PRELOADABLE_BACKENDS="epson2" --with-usb
make
make install
Note it would be great if the epson2.desc file be updated for the new 12000XL
:model "Expression 12000XL"
:interface "USB"
:usbid "0x04b8" "0x015b"
:status :good
:comment "overseas version of the DS-G20000"

I'd gladly do so but ... seeing that you have trouble using it via USB
on your Mac, what makes you confidently say that this should be added to
the epson2.desc file?

Hope this helps,

Hi again,

Post by Olaf Meeuwissen
Hi Tom,
Cc:ing the list for the benefit of everyone.

I have faith that we will get the code to work with High Sierra. I
have now been able to build the software now and in my $B!H(Bspare$B!I(B time
trying to debug why it isn$B!G(Bt connecting. It works on 10.11, but not
10.12 or 10.13 so I am hopeful either I find the problem or the group
finds the issue. I figured since I have access to the 12000XL and
noticed it wasn$B!G(Bt in there I would share it with the group.
Thanks for all the work you do.

on your Mac, what makes you confidently say that this should be added to
the epson2.desc file?

So seeing that it works on 10.11 (but not on 10.12 and 10.13, yet?),
I'll add it to the epson2.desc (and epson2_usb.c) file.

Done. Changes are in d6a93b83.

Hope this helps,
