I followed the instructions I found here (http://ubuntuforums.org/showthread.php?t=108256), which gave a little bit more information about setting up udev.
I got some better activity and feedback, from this command : SANE_DEBUG_SNAPSCAN=255 scanimage -L However, it hangs at sane_snapscan_get_devices, with the following output from the process : [snapscan] atomic_usb_cmd(0,0xbfea70ce,6,0x0,0x0 (0)) [snapscan] usb_cmd(0,0xbfea70ce,6,0x0,0x0 (0)) [snapscan] usb_cmd: cmdlen=6, datalen=0 [snapscan] usb_write: writing: 0x00 0x00 0x00 0x00 0x00 0x00 [snapscan] Written 6 bytes [snapscan] usb_read: reading: 0xfb 0x00 0x00 0x00 0x00 0x00 0x00 0x00 [snapscan] Read 8 bytes [snapscan] 2nd read 4 write 2 [snapscan] snapscani_init_device_structure() [snapscan] sane_snapscan_get_devices (0xbfea8298, 0) and after some time the process starts to take up 100% CPU. What I want to know is if the snapscan backend on its own is enough to drive the scanner, or do I always need the iscan shared libraries from the Avasys website, and if yes, what is the best place to install them ?
