Package: libinklevel5
Version: 0.8.0-1.1+b1
Severity: serious
libinklevel requires /dev/usb/lp? or /dev/usblp? for USB printers. Otherwise, it returns DEV_USB_LP_INACCESSIBLE: 


     case DEV_USB_LP_INACCESSIBLE:
       printf("Could not access '/dev/usb/lp%d' or '/dev/usblp%d'.\n",
              portnumber, portnumber);
       break;


get_device_id() contains:


     if (port == USB) {
       sprintf(device_file1, "/dev/usb/lp%d", portnumber);
       sprintf(device_file2, "/dev/usblp%d", portnumber);
       fd = open(device_file1, O_RDONLY);
       if (fd == -1) {
         fd = open(device_file2, O_RDONLY);
       }
       if (fd == -1) {
         return DEV_USB_LP_INACCESSIBLE;
       }
     }
Therefore, polling ink levels on USB printers fails if the usblp LKM is not loaded: 


$ ink -p usb
Could not access '/dev/usb/lp0' or '/dev/usblp0'.
Could not get ink level.
chealer@vinci:~$
Both ink and Qink fail with USB printers. qink just complains "Printer error No printers detected on this system". Launching it as root won't help. However, printing works...
usblp used to be loaded when a USB printer was plugged in. usblp is now blacklisted by cups, since CUPS switched from usblp to libusb: 


Drop usb-backend-both-usblp-and-libusb.dpatch. It's causing crashes, and
      upstream does not want it either. Instead, add a blacklist file
      debian/local/blacklist-cups-usblp.patch and install it into
      /etc/modprobe.d/; that way, we don't require kernels to disable usblp, and
      allow other spoolers than cups to work.

http://packages.debian.org/changelogs/pool/main/c/cups/current/changelog#version1.4.6-8


# cat /etc/modprobe.d/blacklist-cups-usblp.conf
# cups talks to the raw USB devices, so we need to blacklist usblp to avoid 
# grabbing them
blacklist usblp
root@vinci:/etc#


A workaround is to purge cups, or to manually load usblp.
This means that ink and Qink won't just work for the vast majority of printers.

Changes:
 pythondialog (3.2.0-1) unstable; urgency=low
 .
   [ Florent Rougon ]
   * New upstream release.
 .
   * Add Build-Depends on python3-docutils,
     python3-sphinx (>= 1.0.7+dfsg-1~) and python3-pygments because this
     release brings a new Sphinx-based documentation.
 .
   * add-glossary-label: new patch to add a "glossary" label right before
     the Glossary (maybe upstream bug, but upstream-installed Sphinx didn't
     complain about the missing label!).
 .
   * Build-Depend on python3-doc so that intersphinx can use
     /usr/share/doc/python3/html/objects.inv (since downloading is
     prohibited during package build).
   * use-local-python3-doc-for-cross-references: new patch that:
       - uses /usr/share/doc/python3/html/objects.inv as the inventory file
         for Python cross-references;
       - resolves these references locally (with a
         file:///usr/share/doc/python3/html prefix)
   * Add a Suggests: python3-doc for these references to the local Python
     documentation.
 .
   * Add python3-dialog.doc-base.
 .
   [ Tristan Seligmann ]
   * Import packaging work by Florent Rougon.
     - python-dialog package removed, python3-dialog package added, since only
       Python 3 is supported upstream.
     - Reworked packaging fixes old bugs (closes: #608408, #615432, #646247)
   * Adopt package on behalf of DPMT (closes: #673962).
   * Add VCS control fields.
   * Check PGP signature in debian/watch.
