The attached patch would fix this bug. It adds two rules to skip printers. The second skips all kinds of printers by checking whether the standard interface of a printer is present in the USB device. The first skips HP printers, it is the same rule as HPLIP uses. I have added it because it covers a second interface, which is probably of some weird proprietary HP printer devices. For my printer the bug goes away with this patch, also with any one of the two rules commented out.
I think one can assume that there is no printer available which doubles as a media player. ** Patch added: "69-libmtp.rules.patch" https://bugs.launchpad.net/ubuntu/+source/udev/+bug/1863239/+attachment/5339056/+files/69-libmtp.rules.patch ** Tags added: patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1863239 Title: /dev/bus/usb/*/* device file of HP multi-function printer assigned to "audio" group To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/libmtp/+bug/1863239/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
