I also created the AUR scangearmp2-sane-git which uses the github repository below. It includes a slightly upgraded GUI for scangearmp2, but more importantly provides a sane driver.

This should all be working now. When I have the time I will be looking at the sane version as well. Thanks @dequis for the solution

Just adopted the package, thanks livix. I will update this over the next few days. And might have some time to make a package for the sane backend as well

@dequis Could you share the modified PKGBUILD to apply the patch?

@livix, could you please update?

@dequis Thank you! Just tried out the fix (with v4.30 sources) and it is working well. @livix Please update :)

Best regards

Doesn't actually fix the segfault issue, but it's newer.

Patch to fix the issue:

I don't use usb so I can't guarantee everything else works there. This code assumes libusb will grab the default context, but libusb_init is called with g_context instead of NULL, so the default is never initialized.

Hello, after some recent update, I'm now getting:

$ scangearmp2

Segmentation fault (core dumped)

Any idea how to fix it pls?
