A little bit more info that might help track this problem down: The first time I run hp-scan and it fails (meaning, I connected the printer, scanned, then ran hp-info -i, then ran hp-scan again), it prints the above mentioned SANE: Error during I/O (code=9) The second time I run it, it hangs forever, but dmesg shows this: [ 489.863062] usb 1-1: Process 3992 (hp-scan) called USBDEVFS_CLEAR_HALT for active endpoint 0x01
And it shows that same thing on dmesg each time I kill hp-scan and execute it again. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to hplip in Ubuntu. https://bugs.launchpad.net/bugs/1570955 Title: hp-scan stops working if I run hp-info (several printer models) Status in HPLIP: New Status in hplip package in Ubuntu: New Bug description: I have: Distributor ID: Ubuntu Description: Ubuntu 14.04.4 LTS Release: 14.04 Codename: trusty I downloaded hplip-3.16.3.run and executed it and it installed hplip. I add a USB printer (HP Photosmart B210), and then I run hp-scan and it scans properly. I can run hp-scan any number of times with no problem. Each time I run it I get this on dmesg: [101238.781550] Did not find alt setting 1 for intf 0, config 1 Then I run hp-info -i , I get all the printer info, 3 dmesg errors get generated: [101290.777189] Did not find alt setting 1 for intf 0, config 1 [101290.777686] Did not find alt setting 1 for intf 0, config 1 [101290.778184] Did not find alt setting 1 for intf 0, config 1 And after that, all subsequent calls to hp-scan fail. The first time I type hp-scan after having ran hp-info -i , it shows an error: Using device hpaio:/usb/Photosmart_Plus_B210_series?serial=CN09F1P57X05J9 Opening connection to device... error: SANE: Error during device I/O (code=9) And dmesg also prints: [101355.572440] Did not find alt setting 1 for intf 0, config 1 All the subsequent calls to hp-scan will hang up for ever opening connection to device. and it prints the dmesg error: [101355.572440] Did not find alt setting 1 for intf 0, config 1 At this point I can only kill the process (hp-scan). The only way to make it work again is disconnecting the USB cable, and connecting it back in. But as soon as I run hp-info it goes bad again. The problem does not happen over network. Over network I can always scan and also run hp-info (even at the same time). I tested with 3.15.11 and 3.15.9 and got the same issue. I will go back a little bit more to bisect and post the results later on. I got reports on the exact same problems on a Laserjet m1212 (over USB), and two deskjet 2132. They all print the dmesg error each time hp-info or hp-scan is executed.
