I have one printer. It is a HP Envy 5530. I'm experiencing multiple issues. Sometimes CUPS finds printers, sometimes it doesn't. It auto-adds printers randomly. It auto-deletes printers randomly. One day the printer works, the next it does not.
Also seeing these errors in syslog: Jun 9 12:42:14 yellow hp[34756]: io/hpmud/musb.c 427: Found interface conf=0, iface=0, altset=1, index=3 Jun 9 12:42:14 yellow hp[34756]: io/hpmud/musb.c 389: Active kernel driver on interface=0 ret=0 Jun 9 12:42:14 yellow hp[34756]: io/hpmud/musb.c 515: invalid claim_interface 7/1/4: Device or resource busy Jun 9 12:42:14 yellow hp[34756]: io/hpmud/musb.c 427: Found interface conf=0, iface=3, altset=0, index=9 Jun 9 12:42:14 yellow hp[34756]: io/hpmud/musb.c 389: Active kernel driver on interface=3 ret=0 Jun 9 12:42:14 yellow hp[34756]: io/hpmud/musb.c 515: invalid claim_interface ff/4/1: Device or resource busy Jun 9 12:42:14 yellow hp[34756]: io/hpmud/musb.c 427: Found interface conf=0, iface=0, altset=0, index=11 Jun 9 12:42:14 yellow hp[34756]: io/hpmud/musb.c 389: Active kernel driver on interface=0 ret=0 Jun 9 12:42:14 yellow hp[34756]: io/hpmud/musb.c 515: invalid claim_interface ff/cc/0: Device or resource busy Jun 9 12:42:14 yellow hp[34756]: prnt/backend/hp.c 825: INFO: open device failed stat=21: hp:/usb/ENVY_5530_series?serial=CN57A5636Z05XT; will retry in 30 seconds... ** Attachment added: "Screenshot of duplicate printers in CUPS Find New Printers." https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1875796/+attachment/5503675/+files/screenshot-127.0.0.1_631-2021.06.09-12_38_33%281%29.png -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1875796 Title: HP Envy 5530 printer/scanner does not work To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/cups/+bug/1875796/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
