This brings back memories.  Mind you, they're not particularly good
ones.

The libusb_reset_device() function[1] basically does a disconnect and
reconnect of the device, so usblp claiming it again is not a surprise.

Not that I'm aware of, but you might try modifying your C code to use
the OS specific kernel related libusb APIs[2] to check for an active
kernel driver and detach or attach it as needs be.

 [2]: 
http://libusb.sourceforge.net/api-1.0/group__dev.html#gab14d11ed6eac7519bb94795659d2c971

That's basically what I ended up doing in the sanei_usb.c code for the
third party epkowa backend way back when.  You can find its code at

 http://support.epson.net/linux/src/scanner/iscan/iscan_2.30.3-1.tar.gz

in case you're interested.

I notice that there is now also libusb API that lets you automate this.
Cool, might be something for the sane-backends sanei_usb.c code.

Patches welcome ;-)

Hope this helps,

[sane-devel] Canon Pixma G2000

2017-09-06 Thread Iam Droidzone 
So, with the latest PPA updates, Ubuntu Xenial recognizes my G2000 as a
scanner. But I'm having the issue where usblp is claiming the device,
causing this to appear in dmesg, and the scanning jobs just stutter out:
"usb 1-1.4: usbfs: interface 1 claimed by usblp while 'scangui' sets config
#1"

I tried many workarounds including writing C code to release the device
from usblp as documented here:
https://bugzilla.redhat.com/show_bug.cgi?id=723696#c2

But usblp releases it and then claims it.
scanimage does not work from command line, or via xsane or scangearmp2.

Is there a known resolution?

Hi,

I just added your scanner to SANEs code.

You need to use my ppa:
https://launchpad.net/~rolfbensch/+archive/ubuntu/sane-git . But please
be patient, the ppa will support your scanner with the next version
tomorrow (1.0.27+git20170902).

Hope this helps.

Cheers,
Rolf

usb 0x04a9 0x1795
Normalement c'est le backend pixma que vous devez utiliser.
Par conséquent la ligne doit seulement être ajouter dans pixma.conf
Regarder dans /etc/sane.d/dll.conf
#pixma
remplacer par
