USB (permissions ?) problem on newly installed Bullseye : usb scanner wont communicate
Hi to Everyone, My old Debian Stretch having crashed after last update, I installed Bullseye. Most things operate OK after re-installing, except so far: 'gphoto2' and my Epson Scanner Perfection v500. I have re-installed the scanner using : epsonscan2_6.7.43.0-1_amd64.deb and epsonscan2_non-free-plugin_1.0.0.6-1.deb and the installed went Ok ; the scanner is reckognised and it appears on the list... But it does not operate ! Upon launching, it says: "impossible to communicate with the scanner... Verify if it is connected to usb port and powered on..." then appears a box showing : "EPSON EPSON scanner : USB:001:009", and I can't connect to it. Same thing with "gphoto2" once my camera is connected to usb port : $ gphoto2 --auto-detect => CANON EOS 600D usb: 001,015 OK, it is reckognized... but, now if I type: gphoto2 -L "Impossible to communicate with the USB peripherics..." Back to my scanner : # sane-find-scanner ...Could not fetch... Pipe error found USB scanner vendor=0x04b8 [EPSON] , PRODUCT=0x0130 [EPSON Scanner] at libusb:001:009 ls -l /dev/bus/usb/001/009 crw-rw-rw-+ root root Thanks in advance for your help

I think I should make usb ports accessible to regular users.

flphoto and usb permissions
Hi, I have a fresh install of Debian sarge for a intel pentium iii machine. I have a Kodak CX6200 digital camera that I was able to get working only with flphoto. I created an alien package from the rpm on the flphoto website. The problem I'm having is I can access the camera's photos for root, however, a regular user cannot access the camera. The camera is recognised, but not accessible. I have the hotplug package and even installed usb-perms, but I still have the same problem. If anyone can give me some pointers on how to get the camera accessible to users other than root I would be very appreciative. :-) Sincerely, John Kerr Anderson -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

usb permissions + export display
Hello everybody ! I'm new to Debian but not (quite!) to Linux. I used to run RedHat, and today I'm under Woody. I have to little problems that I never had to deal with under RH: 1. When I plug my didgital usb camera, I can only access it under root, not as a regular user. I know this is because /proc/bus/usb/000/... entries are accessible only by root, and I can't change it since as soon as I re-plug my camera, the permissions are back only for root. Someone mentionned the hotplug package (right now, I'm using usbmgr, I don't really know the difference), but I read the manual and didn't see anything helpfull regarding my problem. 2. I want to export my display on anothre computer. On the server running X, I issued the following command: xhost +, and on the client, when I launch an application, like xterm -display server:0, I get this error message: xterl Xt error: Can't open display: server:0. Isn't it odd since my X server is supposed to accept connections from any host ? Thanks in advance for your help in those 2 problems. Antoine ps: I hope you understood my questions because of my poor English. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

I had the same problem and decided to install the USB perimssion daemon by myself, because I couldn't find any Debian package to deal with that problem. Take a look at http://www.xena.uklinux.net/Linux/usb_perms.html The init script is made for SuSE I think, so you must create one by yourself. 2. I want to export my display on anothre computer. On the server running X, I issued the following command: xhost +, and on the client, when I launch an application, like xterm -display server:0, I get this error message: xterl Xt error: Can't open display: server:0. I seriously recommend to use ssh instead of unencrypted X11 connections. However, It seems that your X server has been started with the -nolisten tcp option for security reasons. Are you using gdm? Look at /etc/gdm/gdm.conf. Using xdm? Try /etc/X11/xdm/Xservers. Change the line that starts the X server you are dealing with (probably :0). Please use ssh instead. Try $ ssh -x client and look at $ echo $DISPLAY It should look like localhost:10 or so. If not, enable X11 forwarding in /etc/ssh/sshd_config at the X11 clients side. When done, just type xterm. Hope this will help you. If not, request more details. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

Thank you for the comment. $ ssh -x client forces ssh to NOT forward X11, even if requested by default. I usually modify /etc/ssh/ssh(d)_config, so that I don't have to use any option at all and so I always mix the options when forced to use one ;-) Thanks, Colin. -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

/proc/bus/usb permissions in Linux 2.4.4 (OT?)
Hi debian-user readers, I'm not sure that this question is appropriate for debian-user, since it's about Linux and not anything Debian-specific. Still, I first sent it to the linux-usb-users mailing list, but that list is very low-traffic, and I haven't heard anything back. So, I thought I'd throw it out to the wide and helpful audience of debian-user. I recently purchased a Kodak DC 4800 digital camera, and have been attempting to get it to work. I was using Woody with Linux 2.2.18, but I kept getting the device not accepting new address (error=-110) error. So, I upgraded to 2.4.4, and now the camera is properly recognized. However, it seems to me that the devmode and devgid mount options for usbdevfs, which worked fine with 2.2.18, no longer do anything. I have the following line in /etc/fstab: usb /proc/bus/usb usbdevfs devmode=0664,devgid=107 0 0 and I get no errors when mounting occurs; however, usb device files always get created with the permissions of 0644 and gid 0. For example: -rw-r--r--1 root root18 May 19 13:20 /proc/bus/usb/001/004 The same thing happens when I mount manually, specifying the devmode and devgid options with -o. Is this a bug, or am I doing something wrong? Are others having success using usbdevfs with these options in 2.4.4? Thanks for any answers you can provide. -- David Steinberg [EMAIL PROTECTED]
