About the terrible noise... Gerhard (or others), do you need any more testing from Winni and me? At the moment, a value of 0.76 for dMaxMotorSpeed seems to be fine for both of us.
Winni, if you still have problems running sane as a non-privileged user, try to read here: http://www.sane-project.org/README.linux and also http://ubuntuforums.org/showthread.php?t=1565846&page=2&s=736558689cd343dc4c4af0d3cabe7a4e(last post) and here: http://manpages.ubuntu.com/manpages/hardy/man5/sane-usb.5.html(LIBUSB section) and also, maybe, here: https://help.ubuntu.com/community/ScanningHowTo#Permission_Issues or simply among here ;-) : http://www.google.it/#q=xsane+works+only+root+ubuntu+12.04 Best regards, Andrea 2013/9/3 Winni <"windose"@kabelmail.de> > Hi, > > with the help of Andrea Vai I was able to modify the file > plustek-usbdevs.c @ line 2064 entering 0.76 for dMaxMotorSpeed. > > After that Andrea Vai showed me via Email recompiling > sane-backends-git20130901 > > Only recompiling did not work, so we had to rename and modify the symbolic > links in /usr/lib/x86_64-linux-gnu/sane from > > libsane-plustek.so -> /usr/lib/sane/libsane-plustek.**so.1.0.22 > libsane-plustek.so.1 -> /usr/lib/sane/libsane-plustek.**so.1.0.22 > > to > > libsane-plustek.so -> /usr/lib/sane/libsane-plustek.**so.1.0.24 > libsane-plustek.so.1 -> /usr/lib/sane/libsane-plustek.**so.1.0.24 > > output scanimage -L > > [sanei_debug] Setting debug level of plustek to 5. > [plustek] Plustek backend V0.52-11, part of sane-backends 1.0.24git > [plustek] Retrieving all supported and conntected devices > [plustek] Available and supported devices: > [plustek] Device: >libusb:006:002< - 0x04a9x0x2206 > [plustek] usbDev_open(auto,) - 0xbcae70 > [plustek] Vendor ID=0x04A9, Product ID=0x2206 > [plustek] usbio_DetectLM983x > [plustek] usbio_DetectLM983x: found LM9832/3 > [plustek] Detected vendor & product ID: 0x04A9-0x2206 > [plustek] Device description for >0x04A9-0x2206< found. > [plustek] usb_initDev(38,0x04a9,-1) > [plustek] Device WAF : 0x00004002 > [plustek] Transferrate: 1000000 Bytes/s > [plustek] Device Flags: 0x00000000 > [plustek] Vendor adjusted to: >Canon< > [plustek] LAMP-STATUS: 0x00000000 (off) > [plustek] RESETTING REGISTERS(-1) - 0x80 > [plustek] MISC I/O after RESET: 0x66, 0x16, 0x91 > [plustek] Calibration file-names set to: > [plustek] >/root/.sane/Canon_CanoScan_**N650U_N656U-coarse.cal< > [plustek] >/root/.sane/Canon_CanoScan_**N650U_N656U-fine.cal< > [plustek] usb_SetScanParameters() > [plustek] usb_GetMCLKDivider() > [plustek] usb_GetMCLKDiv() > [plustek] * PhyBytes = 6 > [plustek] * PhyLines = 4 > [plustek] * TotalBytes = 24 > [plustek] * Scansteps=72 (9*1200/150) > [plustek] usb_SetScanParameters() done. > [plustek] usbDev_getCaps() > [plustek] Scanner information: > [plustek] Vendor : Canon > [plustek] Model : CanoScan N650U/N656U > [plustek] Flags : 0x00000000 > [plustek] drvclose() > [plustek] usbDev_stopScan() > [plustek] usbDev_ScanEnd(), start=0, park=0 > [plustek] usbDev_close() > device `v4l:/dev/video0' is a Noname WebCam SCB-0320N virtual device > device `plustek:libusb:006:002' is a Canon CanoScan N650U/N656U flatbed > scanner > [plustek] Shutdown called (dev->fd=-1, libusb:006:002) > [plustek] Waiting for scanner-ready... > [plustek] Switching lamp off... > [plustek] LAMP-STATUS: 0x00000000 (off) > [plustek] LAMP-STATUS: 0x00000000 (off) > [plustek] Lamp-Timer stopped > > > BUT (!) with KanotixDFx86_64 Distro I can only start the GUI Frontend as > root with [ALT f2] kdesu XSane > > then I get a dialogue-box which tells me in German ( I translate) > > #Warning > #You try to execute XSane as ROOT.
