I think this may be related to bug #424331. To be certain, we need to see what the ACLs are for the relevant device node. To do that, follow these steps: Run '/sbin/lsusb' and find the bus and device numbers for the device, e.g. 003 and 002 here (for my PSC 2210): ... Bus 003 Device 002: ID 03f0:2911 Hewlett-Packard ... Then run this command, substituting in the right numbers: getfacl /dev/bus/usb/003/002 Looks like a similar problem indeed (got a good workaround?): [root@rent rc.d]# lsusb Bus 004 Device 001: ID 0000:0000 Bus 003 Device 004: ID 046d:c001 Logitech, Inc. N48/M-BB48 [FirstMouse Plus] Bus 003 Device 001: ID 0000:0000 Bus 005 Device 001: ID 0000:0000 Bus 002 Device 009: ID 03f0:5711 Hewlett-Packard Bus 002 Device 008: ID 0bc2:3000 Seagate RSS LLC Bus 002 Device 001: ID 0000:0000 [root@rent rc.d]# getfacl /dev/bus/usb/002/009 getfacl: Removing leading '/' from absolute path names # file: dev/bus/usb/002/009 # owner: root # group: lp user::rw- user:moz:rw- #effective:r-- group::rw- #effective:r-- mask::r-- other::r-- This will correct the ACL mask: setfacl -m m:rw- /dev/bus/usb/002/009 Investigation continues as to the cause and resolution of the problem. I have the same problem printing. syslog gives: Jan 9 03:38:00 pent Photosmart_C4100_series?serial=MY64JB90MN04J7: io/hpmud/musb.c 549: invalid product id string: Operation not permitted Jan 9 03:38:00 pent Photosmart_C4100_series?serial=MY64JB90MN04J7: io/hpmud/musb.c 1003: unable to open hp:/usb/Photosmart_C4100_series?serial=MY64JB90MN04J7 Jan 9 03:38:00 pent Photosmart_C4100_series?serial=MY64JB90MN04J7: INFO: open device failed; will retry in 30 seconds... I fiddled with the settings of the usb file until eventually: # getfacl /dev/bus/usb/002/014 getfacl: Removing leading '/' from absolute path names # file: dev/bus/usb/002/014 # owner: root # group: root user::rwx group::r-- mask::rwx other::rwx Your workaround wasn't enough. Here's a history of what I fiddled with: 750 setfacl -m m:rw- /dev/bus/usb/002/014 ... 768 getfacl /dev/bus/usb/002/014 769 ls -l /dev/bus/usb/002/014 770 chmod g+w /dev/bus/usb/002/014 771 ls -l /dev/bus/usb/002/014 772 getfacl /dev/bus/usb/002/014 773 man setfacl 774 chmod 777 /dev/bus/usb/002/014 775 getfacl /dev/bus/usb/002/014 776 lsusb 777 ls /dev/bus/usb/002/012 778 ls /dev/bus/usb/002/014 779 ls -l /dev/bus/usb/002/014 780 getfacl /dev/bus/usb/002/014 781 chmod g+x /dev/bus/usb/002/014 782 getfacl /dev/bus/usb/002/014 783 chgrp root /dev/bus/usb/002/014 784 getfacl /dev/bus/usb/002/014 785 ls -l /dev/bus/usb/002/014 786 ps -ef | grep lpd 787 ls -l /dev/bus/usb/002/014 788 ls -l /dev/bus/usb/002/014 789 getfacl /dev/bus/usb/002/014 (In reply to comment #4) > Your workaround wasn't enough.
