Ubuntu :: LibUSB Not Available To Sane Find Scanner

Apr 21, 2011

I too have what looks like the same problem. I too have read all the relevant man pages and other relevant sites:
Supported devices [URL]
CanoScan LiDE 110 (the printer I've just bought) has "complete" support apparently.
Followed directions here: [URL]
Read: [URl]
Another story of purchasing a "complete"ly supported scanner. [URL]
The solution? Use windows xp in a vm.

I don't think much of that sort of solution. As a temporary work around... ok. I'm running debian lenny.

Slackware :: Sane - After Upgrade To 1.0.22 Cannot Find Scanner

Mar 24, 2011

I have a Samsung SCX-4200. It was working pretty good with sane 1.0.21. I'm using slackware current, keeping updated (almost) every day. On the Mon Feb 28 update sane was updated to sane-1.0.22-i486-1. After that update xsane (as user) cannot find my scanner. I was able to find it running sane-find-scanner as root, but scanimage -L (as root) wasn't able to find the scanner. Now I have updated to the last sane package, named sane-1.0.22-i486-2 . In the changelog I can see that this rebuild should add libusb support.

In fact, now there's no way to find the scanner. And now also sane-find-scanner (as root) is no more able to detect the scanner, also running the command as root. I've tried running sane-find-scanner -v -v and scanimage -v -v -L but I can't get no useful hints. I have checked the sane configuration files but always seems good (the row with USB IDs is not commented in the backend file, which is xerox_mfp, and the backend is listed in dll.conf).

Slackware :: Xsane Does Not Find Scanner And Libusb Permission Error?

Oct 25, 2010

I am tired, and I simply can't find an easy answer.So, today I need the scanner in slackware64 13.1, only to find that it does not work as user. I have an HP Deskjet F2180 and using CUPS it is identified as hp:/usb/Deskjet_F2100_series?serial=CN81H4S2SP04TK.In the past the simple solution was to add oneself to the right groups, but it does not work this time.As user I get:

bash-4.1$ sane-find-scanner

Fedora Hardware :: Sane - Does It See My Scanner Or Not?

Mar 28, 2010

I have a Genius CP-SF600 scanner. I have put the fimware in the necessary directory for the backend (/usr/share/sane/gt68xx), and what I run sane-find-scanner I get:

$ sane-find-scanner
# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.

# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.
found USB scanner (vendor=0x0458, product=0x2021, chip=GT-6816?) at libusb:002:006
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.

# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
# You may want to run this program as root to find all devices. Once you
# found the scanner devices, be sure to adjust access permissions as
# necessary.

However, when I run scanimage -L I get:
$ scanimage -L
No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages). So sane sees the scanner, but then scanimage says it can't find any scanners. If I run scanimage -L as root it does seem to find the scanner.. so its a permissions problem somewhere.. I will keep investigating....

Ubuntu :: Running Scanner From Virtual Box - Not Supported By Sane

Nov 16, 2010

I have and old scanner, Canoscan 3200F, which is not supported by sane. It will not run in Wine, because there is no Sane support. Does anyone know if I was to install a Windows OS in Virtual Box would that enable me to run it or would I have the same problem as I have with Wine?

Debian :: Sane - Share Epson Scanner Over Network

Apr 29, 2010

I have a debian server (squeezzy) amd 64, running with an epson BX-300f pluged to USB. And I want to share the scanner over my network. So let's do that, Intalled sane, sane utils, iscan, which I've downloaded from epson drivers and wich include epkowa drivers fro scanner to work..
after that I installed on my system (Ubuntu 9.10) xsane... on console I type:

root@bruno-laptop:/home/bruno# scanimage -L
*** glibc detected *** scanimage: free(): invalid pointer: 0x00be63d0 ***
WARNING: Unhandled message: interface=org.freedesktop.DBus.Introspectable, path=/, member=Introspect
device 'v4l:/dev/video0' is a Noname HP Webcam virtual device
device 'net:' is a unknown manufacturer unknown device -- use override to select flatbed scanner
device 'net:' is a Epson Stylus BX300F/TX300F/NX300/ME Office 600F flatbed scanner
device 'net:' is a Epson Stylus BX300F/TX300F/NX300/ME Office 600F flatbed scanner

I don't know why I find so much things, if i only have one scanner. Then I opened xsane and found the scanner over network. I chose the epson with epkowa drivers I try to scan something but it dont output nothing and sometimes it gives me "end of file reached". I can put whatever config files here if you want to, just ask. One time it worked fine.. but only half of an image...

Debian Hardware :: Sane Scanner Only Detected By Root

I added myself to the scanner and saned groups, however scanimage -L only detects the device when run as superuser. I think this may be related to [URL].

No scanners were identified. If you were expecting something different, check that the scanner is plugged in, turned on and detected by the sane-find-scanner tool (if appropriate). Please read the documentation which came with this software (README, FAQ, manpages).

Hardware :: HP CM 2320 FXI Scanner And Sane - No Device Detected

Mar 6, 2011

I have a problem here where sane no longer detects my scanner.

Bus 007 Device 002: ID 03f0:5b17 Hewlett-Packard

found USB scanner (vendor=0x03f0 [Hewlett-Packard], product=0x5b17 [HP Color LaserJet CM2320fxi MFP]) at libusb:007:002

scanimage -L

No scanners were identified. xsane reports no devices detected (I have it in French, "Aucun p'rif'rique disponible"). I get the same when I launch xsane as root, so I doubt it is a usb-rules issue. It used to work; I checked /proc/bus/usb, but that is empty.

Software :: Sane Device Information For Network Scanner?

Jul 22, 2011

OS: CentOS 5.6 yesterday i bought a new HP network printer/scanner (OfficeJet Pro 8500). It installed correctly using hplip drivers. I can print and scan without any problem, very nice and fast device. I did some research where the information where the device port is stored in sane, but cannot find anything. I tried to remove my old network device port for my Brother scanner, but did not find the config file where this information is stored. Neither /etc/sane.d/* nor ~/.sane/xsane/* contains this information.

Slackware :: Getting Epson CX5000 Scanner Working With Sane?

Mar 30, 2010

I have been given an Epson CX5000 3-in-1 that I only want to use the scanner part of (I have a laser and hate buying ink). The scanner works, tested under windoze, but xsane and scanimage -L fail to find it. But, lsusb does:
$ /sbin/lsusb
Bus 001 Device 003: ID 04b8:082b Seiko Epson Corp. Stylus DX5050

I saw a post about it under ubuntu that you had to modify
Which doesn't exist on my Slackware 13 install. I hope this Epson runs faster than my Canon FB630U, which takes almost a four minutes to scan a 5x6 photo and forget scanning an 8.5x11 page (go take a nap).

Fedora Hardware :: Sane Drivers And A Scanjet HP4570 Scanner

How to get the Scanner working, as I would expect it to work out of the box. It is one of the scanners that is completely supported, as per SANE web page info. I also have a hp3300c and it found that immediately.

Software :: Sane Parport Canon N640P Scanner / Getting The Dialog 'No Devices Available'?

Apr 20, 2010

1. Unless root chmod's /dev/parport0 to include o+rw, a user running xsane just gets the dialog 'No devices available'. Should the canon_pp driver be installed as su root, perhaps? CUPS uses the same port for printing without problems. Which library or executable needs to have permissions changed to change to run as root?

2. The N640P has a printer output port built in. As I have only one parallel port, I piggy-back my printer through the scanner. This does not work for xsane in Copy mode: nothing prints until I close xsane and then all I get printed is a stream of binary characters, not an image. I guess the canon_pp driver is holding the port open in such a way that CUPS sees the device as being busy. Any ideas on how to combat that? I am a C programmer and quite happy to help by hacking the code, if I have a start point. It irritates me to have to boot the print server into WinXP just so scanning and copying work without fuss.

Fedora :: Error - Found USB Scanner (vendor=0x04a9 [Canon], Product=0x2213 [CanoScan], Chip=GL841?) At Libusb:001:006

Aug 1, 2009

Since installing F11, my Canon LIDE 50 scanner refuses to work. xsane 0.996 produces an error message: Failed to start scanner: Error during device I/O.

sane-find-scanner says it is there: found USB scanner (vendor=0x04a9 [Canon], product=0x2213 [CanoScan], chip=GL841?) at libusb:001:006 But scanimage -L claims: No scanners were identified.except once when it admitted: device `genesys:libusb:001:006' is a Canon LiDE 35/40/50 flatbed scanner

I reluctantly tested the scanner on a Windoze machine and it works perfectly. And it worked perfectly under F10.

Debian Hardware :: After Compiling SANE, "scanimage -L" Does Not Detect The Scanner?

Aug 5, 2010

I found someone who has a CanoScan 9000F (the new Canon flatbed scanner replacing the 8800F which is already supported in SANE 1.0.21), and managed to find out that it also uses the PIXMA protocol (the protocol used in the scanners for Canon's multi-function printer/copier/scanner devices of the PIXUS/PIXMA MP series (and other names depending on sales region).

Support for the scanner has therefore been added in the pixma backend. However, the initial tester is having trouble compiling and configuring SANE from source, so I am hoping there will be some people here who have access to this scanner and can try to help out as well.

After compiling SANE, if "scanimage -L" does not detect the scanner, probably "usb 0x04a9 0x1908" needs to be added to /etc/sane.d/pixma.conf and /usr/local/etc/sane.d/pixma.conf.

After that slow steps need to be taken to get support for the various resolutions, as this scanner as double the number of CCD rows as the 8800F, and can do double the resolution (up to 9600dpi) optically.

Ubuntu :: Canon MX320 Scanner Not Able To Get The XSane Image Scanner To Recognize Scanner?

Jul 11, 2010

I just received a Canon Pixma MX320 as a gift.

I am currently running the Ubuntu 10.04 OS

I was able to get the printer up and running by downloading the printer driver for debian linux (3.1) from the Canon site without any problems.

Unfortunately I am not having the same luck with the scanner.

I tried downloading ScanGear MP for Linux (deb) (1.3) from the same Canon site but have not yet been able to get the XSane Image Scanner to recognize this scanner driver for my Canon.

Ubuntu :: Unable To Find The 'scanner' Drivers?

Mar 10, 2011

I have a CanonMP280 printer and Ubuntu 10.10. Mp280 is not recognized by Ubuntu 10.10. Through 'cybertechhelp' I was very lucky to get the printing drivers to install. So the printer works.

No-one seems to be able to find the 'scanner' drivers and Canon_help is useless. So I must dual-boot with Windows to be able to scan.

Although win7 is a vast improvement on vista. I would much prefer to single-boot with Ubuntu. I tried other Ubuntu and Ubuntu-Based distros, but, the printer-drivers I have, only work in Ubuntu 08.04 - 10.10

I can't use my printer/scanner - it is an Epson TX110. When I try to use Image scan - I get the message; "Could not send the command to scanner. Check the scanner's status."

There is nothing wrong with the MFC apart from not working on Ubuntu 9.10. I have had it connected to another computer that ran Ubuntu 9.01 (I think that was the release used) and it ran fine but now I'm stuck -

I have drivers installed but cant get them to co-operate with me.

Software :: Clients Cannot Find Network Scanner?

Feb 5, 2009

I currently have a network with an older machine, which is (usually) operated in headless mode as a data & backup server, with a fixed IP of I have two client machines, a desktop & a laptop, which use DHCP. All three computers are running Slackware-12.2, the clients with a full install & the server without any X components. I want to set the server to serve a scanner & have been following this link, which is mostly a rewrite of the man page for sane.d. I set up saned per the article, adding the saned:saned user. 'scanimage -L' works for both root & my local user on the server. I can ssh into the server as my desktop user & 'scanimage -L' works. Ditto if I ssh into the server, then 'su -' to root. I can scan either locally from the server or via ssh from the desktop machine. BUT, I cannot get the scanner recognized on the network. On the server, I have this line in /etc/sane.d/saned.conf:

Code: this line in /etc/services:


sane-port 6566/tcp #SANE network scanner daemon & this line in /etc/inetc.conf:


sane-port stream tcp nowait saned:saned /usr/sbin/saned saned

I have changed the line in /etc/sane.d/saned.conf to just "+", for testing. That didn't work either. On the clients, I have these two uncommented lines in /etc/sane.d/net.conf:


My server user is in the same groups, less vboxusers. The server is identified in /etc/hosts & I can connect to it via ssh & mount nfs shares from it. What am I (not) doing that is killing network scanning?
