Issues installing Printer Cups

[Demos]

I got stuck with installing my pogoplug as printing server. Cups is working fine and tested with a canon printer but my epson dx9400F isn´t listed as printer. The dx9400F should be working "perfectly" as openprinting says and the driver is listed under gutenprint which is also installed.

Do I have to install the printer manually?

[WarheadsSE]

Open the cups admin interface and try adding it with auto-detect. If not, then set it up, and use gutenpring for the drivers.

I already tried to auto-detect the printer over Administration->Find New Printer-> "No printers found."
Administration->Add Printer-> no listed local printer. Do you maybe have a link or a hint how i do the set up?

EDIT:
/usr/lib/cups/backend/usb
$this->bbcode_second_pass_code('', 'DEBUG: list_devices
DEBUG: libusb_get_device_list=5
DEBUG2: Printer found with device ID: MFG:EPSON;CMD:ESCPL2,BDC,D4,D4PX,ESCPR1;MDL:Stylus DX9400F;CLS:PRINTER;DES:EPSON Stylus DX9400F; Device URI: usb://EPSON/Stylus%20DX9400F?serial=070000000000000000&interface=1
direct usb://EPSON/Stylus%20DX9400F?serial=070000000000000000&interface=1 "EPSON Stylus DX9400F" "EPSON Stylus DX9400F" "MFG:EPSON;CMD:ESCPL2,BDC,D4,D4PX,ESCPR1;MDL:Stylus DX9400F;CLS:PRINTER;DES:EPSON Stylus DX9400F;" ""')
so I add the printer with:
$this->bbcode_second_pass_code('', 'lpadmin -p EPSON-STYLUS-DX9400F -E -v "usb://EPSON/Stylus%20DX9400F?serial=070000000000000000&interface=1" -P /usr/share/cups/model/C/stp-escp2-dx9400f.5.2.ppd.gz')
but if i print a test page-->"Waiting for printer to become available."
I have even tried
$this->bbcode_second_pass_code('', '"usb://EPSON/Stylus%20DX9400F?serial=070000000000000000')
and
$this->bbcode_second_pass_code('', '"usb://EPSON/Stylus%20DX9400F?"')
EDIT2:

Now I got Autodetection working with:
$this->bbcode_second_pass_code('', 'chmod 0666 /dev/bus/usb/001/005')
The printer is installed and available all jobs are getting completed but the printer is still not printing a job. No Test page and no self test page.
