Ok, as far as I understand, we have 2 models - 4140 and 4150 - which share a same usb pid, but use a different pixma protocol version.
I'm having a look in the pixma backend on how we could deal with this. What report sane-find-scanner and scanimage -L seems right: sane-find-scanner reports info taken from the usb device itself, here the MF4150 (same info as in a lsusb -v) scanimage -L reports the info placed in the pixma backend for this corresponding vid/pid Nicolas Le samedi 30 ao?t 2008 ? 10:47 -0500, Bob Dronski a ?crit : > Nicolas, > > I can only tell you what my MF4150 is reporting--Hope it helps. > > sane-find-scanner reports > found USB scanner (vendor=0x04a9 [Canon Inc.], product=0x26a3 > [MF4100]) at libusb:003:004-04a9-26a3-00-00 > > and scanimage -L reports > device `pixma:04A926A3_SDF7Z0155773B' is a CANON Canon imageCLASS > MF4150 multi-function peripheral > > bob > > On Aug 30, 2008, at 9:07 AM, Nicolas wrote: > > > Hi Dennis, > > > > I feel a bit confused following discussions on MF4140 and MF4150. > > I understand that they share same PID. > > > >> From Daniel's mail, looks like 4140 signs itself as a 4150 > > > > And finally, does pixma backend need a patch to handle MF4140 ? > > > > I can look also if it is possible to handle simply both devices in the > > backend ... > > > > Nicolas > > > > > > Le vendredi 29 ao?t 2008 ? 20:27 -0700, Dennis Lou a ?crit : > >>> From: Bob Dronski <dronski at gmail.com> > >>> Just wondering if any progress has been made and/or if I can do > >>> anything else to help the progress on the MF-4150?
