Package: ipp-usb Version: 0.9.17-3+b4 Severity: normal Dear Maintainer,
Upon upgrading a computer to bullseye, I discovered that the multifunction scanner/printer/fax HP Officejet Pro 8620 became unusable as a scanner, and could not any more be accessed and managed via hp-toolbox. The system did detect the printer to be connected via USB, but was then unable to connect to it, be it via xsane (or any other scanning software) or hp-toolbox. This very effectively made the scanner unusable from the computer. Upon perusing strace and going through the system logs (I suspected some apparmor problem, I had to fix some after the upgrade), I found out instead that the device was already in use by ipp-usb, which prevented xsane and/or hp-toolbox to use it. Upon stopping ipp-usb, I was able to correctly use the multifunction flawlessly. Please, either fix this incompatibility or document it properly, so that users of such USB-connected devices do not get them partially blocked without any clue as to why. I actually did not explicitly select ipp-usb for installation, it was carried over by the overall upgrade from buster to bullseye (don't know exactly by what dependency/recommends). Getting a message upon installation that this might cause problems with xsane would have spared me a few hours of troubleshooting at the moment I really needed the scanner to work (as it always did before). Thanks in advance, best regards Giacomo Mulas
