My printer stopped working yet again, because of the device's permissions. 55-hpmud.rules sets the group to "lp": # Check for AiO products (0x03f0xx11). ATTRS{idVendor}=="03f0", ATTRS{idProduct}=="??11", OWNER="lp", GROUP="lp", MODE="0666" ... But then, 65-permissions.rules sets the group to "usb": SUBSYSTEM=="usb", ENV{DEVTYPE}=="usb_device", GROUP="usb", MODE="664" Reproducible: Always Steps to Reproduce: 1. Try to print Actual Results: Nothing happens Expected Results: It should print
Rename 55-hpmud.rules to e.g. 90-hpmud.rules, so that its assignments take precedence.
Created attachment 134884 [details] 70-hplip.rules I suggest to move the rules to 70-*.rules like libgphoto2 and other rules that change stuff set in our rules (like libusb permissions). The attached file is as I would change the rules. As MODE=0666 is bad for printers. Is this really needed?
I don't suffer this problem, Are you in "lp" and "usb" groups?
(In reply to comment #3) > I don't suffer this problem, Are you in "lp" and "usb" groups? I'm suspecting his user is in lp but not in usb, and to me that seems like a legitimate setup. And since what Matthias suggested seemed to make sense (BTW Matthias, thanks for the crash course on udev) I went ahead and replaced the udev rules. The fix is in hplip-2.7.10 only, so try it. If it didn't work please reopen and provide the result of hp-check plus whatever would seem relevant. Denis.
hplip-2.7.10 fixes everything, thanks. Yes, I'm in the lp group, but not in usb.
