Anyone could make Epson Stylus cx4700 work?

[Anton Galitch]

Hi
I tried to install my epson stylus cx4700 printer, I installed cups, then
gutenprint.
When configuring the printer in kde control center it detected the driver
for stylus cx4700 and a device was /dev/ulpt0  (its has a usb connection).
After doing that I wanted to test it, but it couldnt print anything. neither
it can give me information about ink level. It says "Device is busy".
So could anyone install this printer?
Im installing it in my x86 Freebsd 6.2
Thanks.
