Hi, it seems that there's a problem with your snapscan.conf file. If you're using libusb you *must not* have a device line, i.e. you should delete any line stating /dev/usb/scanner0 or similar. The backend will automatically probe all USB devices for a suitable scanner.
However, in all the logs on pastebin.ca the scanner is correctly identified. Most likely you're using the wrong firmware file. For your scanner the correct file is u176v***.bin (*** may be any 3-digit number, depending on the version of the firmware shipped with the scanner). If this doesn't help please send me a log with SANE_DEBUG_SNAPSCAN=255 of a scan that results in an error message. /Oliver On Monday 26 June 2006 13:39, Mohammed Ahmed wrote: > Dear Oliver > I have weird problem with my sane back end > > I have suse 10.0 retail edition, scanimage (sane-backends) 1.0.15; > backend version 1.0.15 > > > i did all the procedure on the HOW to and i still get that error > > Failed to open device snapscan ;linusb :004:008 error during device > I/O > > even as root > > that is conversation between me and some one on the #sane channel > > http://pastebin.ca/71929 > > that is the debug out put > SANE_DEBUG_SNAPSCAN=255 > http://pastebin.ca/71903 > > > export SANE_DEBUG_SANEI_USB=255 > http://pastebin.ca/71917 > > > we reached a conclusion says that the back end couldn't create usb > device
