[sane-devel] Troubles with PIXMA MX870 and USB
Hi, I got some more info on the router issue and ADF Duplex. ADF Duplex works properly - I just had to set the page count properly or tell the client to scan all available pages (e.g. in gscan2pdf). I hadn't tried very hard at the time of writing and figured it out later this afternoon - sorry for that. Second info is on the router. Although it was supposed to handle the DNS lookup of local ip addresses, it seems it doesn't handle it at all. The wrong DNS entries seem to come from my ISP (Vodafone in Germany). I "solved" the issue by configuring an external DNS server in my router (i.e. the resolv.conf on my computer still is configured to use the router as nameserver, but the router acting as DNS proxy gets information from an independent DNS server - not the one provided by my ISP). So, for now the USB connection (not working at all) is the worst issue (would be faster then wireless networking, I hope ;-)).

To scan in Duplex ADF mode, you need to set 2 pages to scan in Xsane. Otherwise, it will stop at the first page. Did you try that ?

Yes, the purpose is not so much about deciding whether one has to use a different endpoint in normal operation, but about debugging (so that you can see in your own backend if the correct endpoint is used, when things don't work). And also about being able to restore the previous value if an endpoint is used for use one USB operationr.. With that new function, you can store the old endpoint, change it, do your USB operation and restore the old endpoint. That might be useful if a scanner uses one endpoint for most operations, but another endpoint for some very particular operations. I can imagine that the code is clearer if one sets and immediately resets the endpoint for the operation(s) on the less-used endpoint.

[sane-devel] Add function sanei_usb_get_endpoint
Since we now have the possibility to change the endpoint used for a particular USB communication type, we also need a way to retrieve the current endpoint, so that one can e.g. decide whether a switch to a different endpoint is needed at all, or reset the endpoint to the old value after a single usb operation on a different endpoint. Attached is a simple patch that adds this function sanei_usb_get_endpoint to sanei/, plus a range check in sanei_usb_set_endpoint. Okay to push to master or does that already violate the feature freeze?

I will put this on my to-do list to work around this. A solution will take some time and will not be in 1.2.22 as the merge window for new features has already closed. I will see if I can do the change in both the sane backend and in cups-bjnp. I have seen a fritzbox return "noname" when a reverse lookup is done, but this one is definitely even more incorrect. Localhost is normally 127.0.0.1 your work-around is the correct solution for now. I leave your other issue for Nicolas to answer, as he is the maintainer of the backend kind regards, Louis

[sane-devel] Add function sanei_usb_get_endpoint
I will not complain if you commit, but I don't understand the point. You are not saving any cycles when you look up the value instead of just setting it. It's the same switch(), touching the same variable. Plus, if you DO decide you need to change it, you now have to call a second function. Your code now does more operations, not less. allan On Mon, Jan 31, 2011 at 3:31 PM, Reinhold Kainhofer wrote: > Since we now have the possibility to change the endpoint used for a particular > USB communication type, we also need a way to retrieve the current endpoint, > so that one can e.g. decide whether a switch to a different endpoint is needed > at all, or reset the endpoint to the old value after a single usb operation on > a different endpoint. > > Attached is a simple patch that adds this function sanei_usb_get_endpoint to > sanei/, plus a range check in sanei_usb_set_endpoint.

It seems like the snmp auto-detection really needs net-snmp 5.6 :( In net-snmp 5.5 the UDP broadcast option was added, but apparently the devs missed to add a public-API method of extracting the responding IP address to the broadcast package. In 5.5 the netsnmp_udp_addr_pair struct was used in snmplib/snmpUDPDomain.cc, but that structure was never made public in any header file, so there was not way to get the IP address of the responding scanner. In net-snmp 5.6, the new netsnmp_indexed_addr_pair struct provides access to that information, so I now increased the required net-snmp version to 5.6, as 5.5 does not provide the required functionality...

[sane-devel] Troubles with PIXMA MX870 and USB
Hi folks, I just got a new Canon Pixma MX870, but it doesn't work completely, yet. Let me start with my setup. I run Gentoo with kernel 2.6.36-gentoo-r5 on an Intel(R) Core(TM)2 Duo CPU T9300. I use the latest sane-backends from GIT and sane-frontends-1.0.14. I want to run the scanner in two different configurations - via wireless network and via usb. I'll start with the wireless setup. First of all, it recognizes my printer - kind of. My router (EasyBox 803) resolves all ip addresses in the local network as "localhost" and thereby confuses SANE. # /usr/libexec/cups/backend/bjnp network bjnp://localhost:8611 "Canon MX870 series" "Canon MX870 series localhost" "MFG:Canon;CMD:BJL,BJRaster3,BSCCe,NCCe,IVEC,IVECPLI;SOJ:TXT01,BJNP2;MDL:MX870 series;CLS:PRINTER;DES:Canon MX870 series;VER:1.030;STA:10;FSI:04;HRI:EU;MSI:DAT,E3,HFSF;PDR:4;" If I add the line "bjnp://192.168.2.101:8612" to /etc/sane.d/pixma.conf, scanimage and other applications recognize my scanner and work properly. I attached the log file corresponding to # export SANE_DEBUG_PIXMA=3 # scanimage -T 2> scan-net.log ADF is working, too, but I didn't get "ADF Duplex" running (Xsane scans one page and then stops - is this supposed to work, anyways?). Now trying USB cable, I removed the extra line from /etc/sane.d/pixma.conf. After attaching the USB cable, I get # dmesg -c usb 2-2.1: new high speed USB device using ehci_hcd and address 8 usblp0: USB Bidirectional printer dev 8 if 1 alt 0 proto 2 vid 0x04A9 pid 0x1743 scsi7 : usb-storage 2-2.1:1.2 usblp1: USB Bidirectional printer dev 8 if 3 alt 0 proto 2 vid 0x04A9 pid 0x1743 scsi 7:0:0:0: Direct-Access CanonMX870 series 0103 PQ: 0 ANSI: 2 sd 7:0:0:0: Attached scsi generic sg2 type 0 sd 7:0:0:0: [sdb] Attached SCSI removable disk I also attached the gzipped output of # lsusb -v > lsusb.log Now I ran # scanimage -T 2> scan-usb.log The scanner makes some noises, but the command returns immediately. Xsane fails with "Error during read: Error during device I/O". In some forum I read that unloading ehci_hcd helps. Thus I tried # sudo rmmod ehci_hcd # scanimage -T 2> scan-usb2.log The scanner shows "Processing... Please wait momentarily.", but makes no noises of activity. Since scanimage gets stuck, I terminated it with kill -9. The "Processing..." message only disappears on unplugging the USB connection. Do you have any suggestions?

[sane-devel] How to get infrared image data with sane on an epson v700 scanner?
There is some code in sane to expose additional image types like jpeg and IR. It is disabled because it's not compatible with the sane specification. It does work with scanimage, however. So, you would need to get usb logs of either the windows driver or vuescan making an IR second pass, and figure out how to make those same calls from within the backend. allan On Mon, Jan 31, 2011 at 8:21 AM, Alain Culos wrote: > Hi all, > > I have unsuccessfully scanned the archives and the Internet at large for > relevant answers.
