EPSON Ecoprint ET-2711 cannot install scanner

So I have a EPSON Ecoprint ET-2711. I got the printer to run but I have trouble with the scanner.

I installed Imagescan.

Then I run utsushi and try to select the usb were the scanner is located.

When I select the USB I get:

Cannot access esci:usb:/sys/devices/pci0000:00/0000:00:1a.7/usb9/9-5/9-5:1.0
(esci:usb:/sys/devices/pci0000:00/0000:00:1a.7/usb9/9-5/9-5:1.0)
No such device

So what can I do?

Also I tried sane-find-scanner:

[sandro@sandro-pc ~]$ sudo sane-find-scanner
[sudo] password for sandro: 

  # 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.
  # Also you need support for SCSI Generic (sg) in your operating system.
  # If using Linux, try "modprobe sg".

  # No USB scanners found. If you expected something different, make sure that
  # you have loaded a kernel driver for your USB host controller and have setup
  # the USB system correctly. See man sane-usb for details.

  # Not checking for parallel port scanners.

  # Most Scanners connected to the parallel port or other proprietary ports
  # can't be detected by this program.

And scanimage -L:

[sandro@sandro-pc ~]$ scanimage -L
device `utsushi:esci:usb:/sys/devices/pci0000:00/0000:00:1a.7/usb9/9-5/9-5:1.0' is a   
device `utsushi:esci:networkscan://192.168.0.2:1865' is a EPSON DS-5500 
device `utsushi:sane::epkowa:usb:0x04b8:0x0848' is a  Stylus Office BX300F

Forget all of it. The scanner works well. I just forgot that this epson printer falls asleep automatically so you have to push the power button to turn it on again.
