Hello, I've never set up a scanner on gentoo (or any other linux before).
So here's what I've done. Looking at the sane website I see support for these models: http://www.sane-project.org/man/sane-hp5590.5.html ScanJet 7650 is listed as basic support. I have a HP Scanjet 7670, so it should work? lsusb lists the devices like this: Bus 002 Device 001: ID 1d6b:0001 Bus 001 Device 001: ID 1d6b:0002 dmesg shows nothing. sane-find-scanner reveals this: 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=0x0403 [FTDI], product=0x6001 [UC232R]) at libusb:002:002 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. so am I out of luck? I have this installed: media-gfx/sane-backends-1.0.19-r2 USE="ipv6 usb v4l -doc -gphoto2" replugging the usb cable does not make the device appear on the usb bus? any ideas? James
