Comment 4 for bug 181242

HPLIP accesses printers via libusb and not via the usblp kernel module. So the bug can be in

- Kernel: Lower-level USB modules
- UDEV: Problem in permission assignment of /dev/bus/usb/XXX/YYY files
- libusb (task added)
- HPLIP: Requirement for update to fit to recent changes

The "usb" backend of CUPS is able to find and access the printers, so the usblp kernel module seems to be OK, at least for HP printers.

I consider the problem critical because there is a loss of most important functionalities of HP printers and MF devices connected via USB:

- No borderless printing
- No scanning
- No memory card access
- No faxing
- No ink level check and nozzle cleaning

Ethernet/WLAN-connected HP devices are not affected.

I am using Hardy and did the last full update around five hours ago. I have also rebooted after yesterday's kernel update.
