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 brebs@sent.com 2007-11-01 06:38:49 0000 Rename 55-hpmud.rules to e.g. 90-hpmud.rules, so that its assignments take precedence. zzam@gentoo.org 2007-11-01 13:24:46 0000 Created an attachment (id=134884) 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? pacho@gentoo.org 2007-11-18 18:58:51 0000 I don't suffer this problem, Are you in "lp" and "usb" groups? calchan@gentoo.org 2007-11-19 16:42:20 0000 (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. dima@gmail.com 2007-11-21 06:19:50 0000 hplip-2.7.10 fixes everything, thanks. Yes, I'm in the lp group, but not in usb. 134884 2007-11-01 13:24 0000 70-hplip.rules 70-hplip.rules text/plain IyBVZGV2IHJ1bGVzIGZpbGUgZm9yIEhQIHByaW50ZXIgcHJvZHVjdHMuCgpBQ1RJT04hPSJhZGQi LCBHT1RPPSJocG11ZF9ydWxlc19lbmQiCgojIElzIHRoaXMgbmVlZGVkPyBkZWZhdWx0IHNob3Vs ZCBiZSByb290OmxwIHdpdGggbW9kZSAwNjYwIGFuZCBhbHJlYWR5IHNldCBpbiBkZWZhdWx0IHJ1 bGVzCiNTVUJTWVNURU09PSJwcGRldiIsIE9XTkVSPSJscCIsIEdST1VQPSJscCIsIE1PREU9IjA2 NjYiCgpTVUJTWVNURU0hPSJ1c2J8dXNiX2RldmljZSIsIEdPVE89ImhwbXVkX3J1bGVzX2VuZCIK U1VCU1lTVEVNPT0idXNiIiwgRU5We0RFVlRZUEV9IT0idXNiX2RldmljZSIgLEdPVE89ImhwbXVk X3J1bGVzX2VuZCIKCiMgQ2hlY2sgZm9yIEFpTyBwcm9kdWN0cyAoMHgwM2YweHgxMSkuCkFUVFJT e2lkVmVuZG9yfT09IjAzZjAiLCBBVFRSU3tpZFByb2R1Y3R9PT0iPz8xMSIsIEdST1VQPSJscCIK IyBDaGVjayBmb3IgUGhvdG9zbWFydCBwcm9kdWN0cyAoMHgwM2YweHgwMikuCkFUVFJTe2lkVmVu ZG9yfT09IjAzZjAiLCBBVFRSU3tpZFByb2R1Y3R9PT0iPz8wMiIsIEdST1VQPSJscCIKIyBDaGVj ayBmb3IgQnVzaW5lc3MgSW5ramV0IHByb2R1Y3RzICgweDAzZjB4eDEyKS4KQVRUUlN7aWRWZW5k b3J9PT0iMDNmMCIsIEFUVFJTe2lkUHJvZHVjdH09PSI/PzEyIiwgR1JPVVA9ImxwIgojIENoZWNr IGZvciBEZXNramV0IHByb2R1Y3RzICgweDAzZjB4eDA0KS4KQVRUUlN7aWRWZW5kb3J9PT0iMDNm MCIsIEFUVFJTe2lkUHJvZHVjdH09PSI/PzA0IiwgR1JPVVA9ImxwIgojIENoZWNrIGZvciBMYXNl ckpldCBwcm9kdWN0cyAoMHgwM2YweHgxNykuCkFUVFJTe2lkVmVuZG9yfT09IjAzZjAiLCBBVFRS U3tpZFByb2R1Y3R9PT0iPz8xNyIsIEdST1VQPSJscCIKCkxBQkVMPSJocG11ZF9ydWxlc19lbmQi
