Slackware :: Error - Libusb Couldn't Open USB Device /dev/bus/usb/001/001: Permission Denied

Mar 24, 2011

Hello,

this error spams about 100 times, then the scanner does indeed work. So I'm not completely broken, but the error messages are of concern, and it slows down the process of scanning for the time it takes to do the messages.

Error in console:

libusb couldn't open USB device /dev/bus/usb/001/001: Permission denied. libusb requires write access to USB device nodes.

my sript runs:

scanimage
--device $MODEL
--resolution=$RESOLUTION
-x 5104 -y 6840

my groups:

uid=1000(fogie) gid=100(users) groups=100(users),7(lp),11(floppy),12(mail),15(man),17(audio),18(video),19(cdrom),20(games),21(sloca te),83(plugdev),84(power),86(netdev),93(scanner)

Even a simple:

scanimage -Lv

in console gives this on a separate --current pc as well.

OpenSUSE Network :: IPP Printing Error "libusb Couldn't Open USB Device"

Feb 12, 2010

I have an HP OfficeJet 5610v installed on my system, and cups can print the test page. I can also get the test page to print via [URL] which appears to be printed under the anonymous user. Now if I attempt to print the test page via the printer control panel from windows, I get the following sets of error:

D [11/Feb/2010:11:21:29 -0500] [Job 6] libusb couldn't open USB device /dev/bus/usb/001/001: Permission denied.

CUPS is showing that the "user" is my XP login name so I added that user to Linux and even added that account to the "lp" group and still get the above errors.

Ubuntu :: Error: "Note: Cannot Open TUN/TAP Dev /dev/net/tun: Permission Denied (errno=13)"

I have a problem setting up a TUN interface for OpenVPN. Running OpenVPN gives me this error: "Note: Cannot open TUN/TAP dev /dev/net/tun: Permission denied (errno=13)"

Which i tracked down to: "WARNING: Couldn't open directory /lib/modules/2.6.18-164.15.1.el5.028stab068.9: No such file or directory" (if i run /sbin/modproble tun). Does anyone know how to fix this?

CentOS 5 :: Su: Unable To Open Admin Password File: Permission Denied

when I try to su, with the right password I know it is because I have reset it with a sudo, it says su: incorrect password. Looking at /var/log/messages I see su: Unable to open admin password file: Permission denied. This must mean that the file has incorrect permissions and or owner/group. I am wondering if anyone knew where the file was located and the correct permissions/owner/group.

Slackware :: Bugzilla - Permission Denied - Clean Install Of 13.1

Jul 24, 2010

I didn't back up the blasted /etc/httpd stuff.

I do a "clean" root-only install; i.e., the only partitions that are formatted are the root and usr partition leaving the others untouched (so I don't have to restore the entire thing every time or fiddle with updating). That leaves almost everything in place with only a few edits and additions to make to get back in business; smart and dumb and the same time, sigh.

The partitions look like this for what it's worth:

Code:

Anyway, my web server comes up just fine and other applications work as expected except for Bugzilla and I can't remember what the heck it is I have to do to get it going again. I add a file, httpd-bugzilla.conf in the extra directory and include it at the end of httpd.conf:

Code:

In the above, /var/www/htdocs/bugzilla is not a symbolic link, Bugzilla is actually installed there (and has worked just fine for a long, long time). And, yeah, I know I'm not really supposed to do that but there it is.

I also run checksetup.pl which completes cleanly (it also sets permission masks and group) and double-check that localconfig looks like it ought to.

Seems like that ought to do it, but...

Ubuntu :: PHP Not Working - Warning: Unknown: Failed To Open Stream: Permission Denied

Mar 10, 2010

I just isntalled LAMP using tasksel and have a problem. Whenever I try to access a page (aside from phpmyadmin, that works well), I get this error... Code: Warning: Unknown: failed to open stream: Permission denied in Unknown on line 0 Fatal error: Unknown: Failed opening required '/var/www/index.php' (include_path='.:/usr/share/php:/usr/share/pear') in Unknown on line 0

I have restarted the computer, restarted apache, etc and still nothing. When I first installed, phpmyadmin was inaccessible, so I ran some command in terminal which apparently created a symlink between phpmyadmin in the user/share dir to the /var/www dir, and curious if this is the problem. I have no clue how to remove this symlink if this is the case, and have phpmyadmin working now due to install using sudo apt-get install phpmyadmin.

Ubuntu :: Error(13): Permission Denied

Dec 7, 2010

I have a shared directory on another machine but I can't get it to mount. The permission denied doesn't say where/which permission is denied. Is it on the remote on on the local machine? The remote has sharing enabled for the shareddocs directory and after I have mkdir'ed the local mount point I open it's permissions too.

The verbose response from mount.cfis looks like this:

mount.cifs kernel mount options: unc=//192.168.1.102shareddocs,domain=WORKGROUP,ver=1,rw ,username=clive,,,,,,,,,,,ip=192.168.1.102,pass=** ******

Refer to the mount.cifs( manual page (e.g. man mount.cifs) The man page does not have a list of error codes.

When trying to mount samba share off of domain member server sysimage in Windows receive error "There are currently no logon servers available to service this logon request". When trying to mount.cifs from PDC to samba share on sysimage receive error "mount error(13): Permission denied".

PDC is ClearOS 5.2 named "dc0"

dc0 is configured correctly to my knowledge, windows machines can join domain, domain users can log into windows machines, user directories are mapped properly, logon scripts run properly. sysimage ldap authentication is set up as shown in "Procedure 7.1.

OpenSUSE :: Cdrecord Has No Permission To Open The Device?

Jan 7, 2010

Still getting the "cdrecord has no permission to open the device" error when trying to burn an iso image to a DVD-RW.

I did yet another clean install of openSUSE 11.2 64 on my desktop computer, did updates, added Nvidia and Packman repos (it's not a repo problem as I tried it several times on a totally clean install), added codecs and stuff as advised by caf.

I updated the DVD drive firmware earlier today.

My user is a member of ALL groups.

Drive is an LG GH22NSS50 (sata)

It all works (with the same DVD-RW) under winxp on the same machine.

Is it HAL or something else that blocks permission to devices?

I'm really getting sick to death of this problem, and would be happy just to get rid of anything blocking permissions to the DVD drive.
